The omero::api module defines all the central verbs for working with OMERO.blitz.
Arguments and return values consist of those
types defined in the other ice files available here. With no further custom code, it is possible to interoperate with OMERO.blitz simply via the definitions here. Start with the ServiceFactory definition at the end of this file.
Note: Using these types is significantly easier in combination with
the JavaDocs of the OMERO.server, specifically the ome.api package. Where not further noted below, the follow mappings between ome.api argument types and omero::api argument types hold:
| ome.api | omero::api |
| java.lang.Class | string |
| java.util.Set | java.util.List/vector |
| IPojo options (Map) | omero::sys::ParamMap |
| If null needed | omero::RType subclass |
| ... | ... |
Bases: Ice.Object
Primary callback interface for interaction between client and server session (“”ServiceFactory””). Where possible these methods will be called one-way to prevent clients from hanging the server.
Heartbeat-request made by the server to guarantee that the client is alive. If the client is still active, then some method should be made on the server to update the last idle time.
The session to which this ServiceFactory is connected has been closed. Almost no further method calls (if any) are possible. Create a new session via omero.client.createSession()
Message that the server will be shutting down in the given number of milliseconds, after which all new and running method invocations will receive a CancelledException.

Bases: omero.api.StatefulServiceInterface
Stateful service for generating OME-XML or OME-TIFF from data stored in OMERO. Intended usage:
ExporterPrx e = sf.createExporter();
// Exporter is currently in the “configuration” state // Objects can be added by id which should be present // in the output.
e.addImage(1);
// As soon as a generate method is called, the objects // added to the Exporter are converted to the specified // format. The length of the file produced is returned. // No more objects can be added to the Exporter, nor can // another generate method be called.
long length = e.generateTiff();
// As soon as the server-side file is generated, read() // can be called to get file segments. To create another // file, create a second Exporter. Be sure to close all // Exporter instances.
long read = 0 byte[] buf; while (true) { buf = e.read(read, 1000000); // Store to file locally here if (buf.length
Adds a single image with basic metadata to the Exporter for inclusion on the next call to getBytes().
Generates an OME-TIFF file. The return value is the length of the file produced. This method ends configuration.
Generates an OME-XML file. The return value is the length of the file produced.
Returns “”length”” bytes from the output file. The file can be safely read until reset() is called.

Access to server configuration. These methods provide access to the state and configuration of the server and its components (e.g. the database). However, it should not be assumed that two subsequent calls to a proxy for this service will go to the same server due to clustering.
Not all possible server configuration is available through this API. Some values (such as DB connection info, ports, etc.) must naturally be set before this service is accessible.
Manages synchronization of the various configuration sources internally. It is therefore important that as far as possible all configuration changes take place via this interface and not, for example, directly via java.util.prefs.Preferences.
Also used as the main developer example for developing (stateless) ome.api interfaces. See source code documentation for more.

Provides methods for dealing with the core “Pojos” of OME. Included are: Projects, Datasets, Images.
Read API
The names of the methods correlate to how the function operates:
load: start at container objects and work down toward the leaves, returning hierarchy (Project->Dataset->Image find: start at leaf objects and work up to containers, returning hierarchy get: retrieves only leaves in the hierarchy (currently only Images)
Options Mechanism
The options are used to add some constraints to the generic method e.g. load hierarchy trees images for a given user. This mechanism should give us enough flexibility to extend the API if necessary, e.g. in some cases we might want to retrieve the images with or without annotations
Most methods take such an options map which is built on the client-side using the Parameters class. The currently supported options are:
annotator(Integer): If key exists but value null, annotations are retrieved for all objects in the hierarchy where they exist; if a valid experimenterID, annotations are only retrieved for that user. May not be used be all methods. Default: all annotations leaves(Boolean): if FALSE omits images from the returned hierarchy. May not be used by all methods. Default: true experimenter(Integer): enables filtering on a per-experimenter basis. This option has a method-specific (and possibly context-specific) meaning. Please see the individual methods. group(Integer): enables filtering on a per-group basis. The experimenter value is ignored if present and instead a similar filtering is done using all experimenters in the given group.
Write API
As outlined in TODO, the semantics of the Omero write API are based on three rules:
IObject-valued fields for which isLoaded() returns false are assumed filtered Collection-valued fields that are null are assumed filtered Collection-valued fields for which getDetails().isFiltered(String collectionName) returns true are assumed filtered. TODO: should we accept isFiltered for all fields?
In each of these cases, the server will reload that given field before attempting to save the graph.
For all write calls, the options map (see below) must contain the userId and the userGroupId for the newly created objects. TODO umask.
Creates the specified data object.
A placeholder parent object is created if the data object is to be put in a collection.
For example, if the object is a Dataset, we first create a Project as parent then we set the Dataset parent as follows: //pseudo-code TODO Project p = new Project(id,false); dataset.addProject(p);
then for each parent relationship a DataObject omero.model.ILink is created.
IObject. Supported: Project, Dataset, Annotation, Group, Experimenter. Not null.
options Parameters as above.
Convenience method to save network calls. Loops over the array of IObjects calling createDataObject.
Parameters as above.
Retrieves hierarchy trees in various hierarchies that contain the specified Images.
This method will look for all the containers containing the specified Images and then for all containers containing those containers and on up the container hierarchy.
This method returns a Set with all root nodes that were found. Every root node is linked to the found objects and so on until the leaf nodes, which are omero.model.Image objects. Note that the type of any root node in the returned set can be the given rootNodeType, any of its containees or an omero.model.Image.
For example, say that you pass in the ids of six Images: i1, i2, i3, i4, i5, i6. If the P/D/I hierarchy in the DB looks like this:
Then the returned set will contain p1, d3, i5, i6. All objects will be properly linked up.
Finally, this method will only retrieve the nodes that are connected in a tree to the specified leaf image nodes. Back to the previous example, if d1 contained image img500, then the returned object would not contain img500. In a similar way, if p1 contained ds300 and this dataset weren’t linked to any of the i1, i2, i3, i4, i5, i6 images, then ds300 would not be part of the returned tree rooted by p1.
top-most type which will be searched for Can be omero.model.Project. Not null.
imageIds
Contains the ids of the Images that sit at the bottom of the trees. Not null.
options
Parameters as above. annotator used. experimenter|group may be applied at the top-level only or at each level in the hierarchy, but will not apply to the leaf (Image) level. Returns:
A Set with all root nodes that were
found.
Counts the number of members in a collection for a given object. For example, if you wanted to retrieve the number of Images contained in a Dataset you would pass TODO.
The fully-qualified classname of the object to be tested
property
Name of the property on that class, omitting getters and setters.
ids
Parameters. Unused. Returns:
A map from id integer to count integer
Retrieves images by options.
Parameters as above. No notion of leaves. experimenter|group apply at the Image level and must be present. OPTIONS: - startTime and/or endTime should be Timestamp.valueOf(“YYYY-MM-DD hh:mm:ss.ms”). acquisition data is only relevant for images. Returns:
A set of images.
Given a list of IDs of certain entity types, calculates which filesets are split such that a non-empty proper subset of their images are referenced, directly or indirectly, as being included. The return value lists both the fileset IDs and the image IDs in ascending order, the image ID lists separated by if they were included. Warning: following discussion in trac ticket 11019 the return type may be changed. Arguments:
included the entities included options parameters, presently ignored
Retrieve a user’s (or all users’) images within any given container. For example, all images in project, applying temporal filtering or pagination.

options
Parameters as above. No notion of leaves. experimenter|group apply at the Image level. OPTIONS: - startTime and/or endTime should be Timestamp.valueOf(“YYYY-MM-DD hh:mm:ss.ms”);
limit and offset are applied at the Image-level. That is, calling with Dataset.class, limit == 10 and offset == 0 will first perform one query to get an effective set of rootNodeIds, then getImages will be called with an effective rootNodeType of Image.class and the new ids.
acquisition data is only relevant for images. Returns:
A set of images.
Retrieves a user’s images.
Parameters as above. No notion of leaves. experimenter|group apply at the Image level and must be present. Returns:
A set of images.
Convenience method for creating links. Functionality also available from createDataObject
Retrieves hierarchy trees rooted by a given node (unless orphan is specified – See below)
This method also retrieves the Experimenters linked to the objects in the tree. Similarly, all Images will be linked to their Pixel objects if included.
Note that objects are never duplicated. For example, if an Experimenter owns all the objects in the retrieved tree, then those objects will be linked to the same instance of omero.model.Experimenter. Or if an Image is contained in more than one Dataset in the retrieved tree, then all enclosing omero.model.Dataset objects will point to the same omero.model.Image object. And so on.
The type of the root node. Can be omero.model.Project, omero.model.Dataset, omero.model.Screen or omero.model.Plate. Cannot be null.
rootIds
The ids of the root nodes. Can be null if an Experimenter is specified in options, otherwise an Exception is thrown to prevent all images in the entire database from being downloaded.
options
Parameters as above. annotator, leaves, orphan, acquisition data used. acquisition data is only relevant for images and taken into account if the images are loaded. If rootNodeIds==null, experimenter|group must be set and filtering will be applied at the Class-level; e.g. to retrieve a user’s Projects, or user’s Datasets. If rootNodeIds!=null, the result will be filtered by the experimenter|group at the Image and intermediate levels if available. Due to the amount of data potentially linked a Screen/Plate, the leaves option is not taken into account when the root node is a omero.model.Screen. orphan implies that objects which are not contained in an object of rootNodeType should also be returned. Returns:
a set of hierarchy trees. The requested node as
root and all of its descendants. The type of the returned value will be rootNodeType, unless orphan is specified in which case objects of type rootNodeType and below may be returned.
Retrieves a collection with all members initialized (“loaded”). This is useful when a collection has been nulled in a previous query.
public final static String from the IObject.class
options
Parameters. Unused. Returns:
An initialized collection.
Removes links between OmeroDataObjects e.g Project-Dataset, Dataset-Image Note that the objects themselves aren’t deleted, only the Link objects.
Updates a data object.
To link or unlink objects to the specified object, we should call the methods link or unlink. TODO Or do we use for example dataset.setProjects(set of projects) to add. Tink has to be set as follows dataset->project and project->dataset.
Alternatively, you can make sure that the collection is exactly how it should be in the database. If you can’t guarantee this, it’s best to send all your collections back as null

Provides methods for directly querying object graphs. As far as is possible, IQuery should be considered the lowest level DB-access (SELECT) interface. Unlike the omero.api.IUpdate interface, using other methods will most likely not leave the database in an inconsistent state, but may provide stale data in some situations.
By convention, all methods that begin with get will never return a null or empty java.util.Collection, but instead will throw a omero.ValidationException.
Searches based on provided example entity. The returned entities will be limited by the omero.sys.Filter object.
Note: findAllbyExample does not operate on the id field. For that, use find, get, findByQuery, or findAllByQuery
Executes a full text search based on Lucene. Each term in the query can also be prefixed by the name of the field to which is should be restricted.
Examples:
owner:root AND annotation:someTag file:xml AND name:hoechst
For more information, see Query Parser Syntax
The return values are first filtered by the security system.
Currently the parameters themselves are unused. But the omero.sys.Parameters#theFilter can be used to limit the number of results returned (omero.sys.Filter#limit) or the user for who the results will be found (omero.sys.Filter#ownerId). Returns:
A list of loaded omero.model.IObject
instances. Never null.
Executes the stored query with the given name. If a query with the name cannot be found, an exception will be thrown.
The queryName parameter can be an actual query String if the StringQuerySource is configured on the server and the user running the query has proper permissions.
Queries can only return lists of omero.model.IObject instances. This means all must be of the form:
select this from SomeModelClass this ...
though the alias “this” is unimportant. Do not try to return multiple classes in one call like:
select this, that from SomeClass this, SomeOtherClass that ...
nor to project values out of an object:
select this.name from SomeClass this ...
If a page is desired, add it to the query parameters.
Searches a given field matching against a String. Method allows for case sensitive or insensitive searching using the (I)LIKE comparators. Result set will be reduced by the omero.sys.Filter instance.

Looks up an entity by class and id. If no such objects exists, return a null.
Looks up an entity by class and id. If no such object exists, an exception will be thrown.
Return a sequence of omero.RType sequences.
Each element of the outer sequence is one row in the return value. Each element of the inner sequence is one column specified in the HQL.
omero.model.IObject instances are returned wrapped in an omero.RObject instance. Primitives are mapped to the expected omero.RType subclass. Types without an omero.RType mapper if returned will throw an exception if present in the select except where a manual conversion is present on the server. This includes:
omero.model.Permissions instances are serialized to an omero.RMap containing the keys: perms, canAnnotate, canEdit, canLink, canDelete
The quantity types like omero.model.Length are serialized to an omero.RMap containing the keys: value, unit, symbol
As with SQL, if an aggregation statement is used, a group by clause must be added.
Examples:
select i.name, i.description from Image i where i.name like ‘%.dv’
select tag.textValue, tagset.textValue from TagAnnotation tag join tag.annotationLinks l join l.child tagset
select p.pixelsType.value, count(p.id) from Pixel p group by p.pixelsType.value

Utility service for managing and launching scripts for execution by the Processor API.
Typical usage might include (PYTHON):
sf = client.createSession() svc = sf.getScriptService() scripts = svc.getScripts()
if len(scripts) >= 1: script_id = svc.keys()[-1] else: script_id = svc.uploadScript(‘/test/my_script.py’, SCRIPT_TEXT)
params = svc.getParams(script_id)
# You will need to parse the params to create the proper input inputs = {}
# The last parameter is how long to wait as an RInt proc = svc.runScript(script_id, inputs, None) try: cb = omero.scripts.ProcessCallbackI(client, proc) while not cb.block(1000): # ms. pass cb.close() rv = proc.getResults(0) finally: proc.close(False)
See OMERO.scripts for more information.
Returns true if there is a processor which will run the given script.
Either the script is an official script and this method will return true (though an individual invocation may fail with an omero.ResourceError for some reason) or this is a user script, and a usermode processor must be active which takes the scripts user or group.
Delete the script on the server with id. The file will also be removed from disk.
Modify the text for the given script object.
Get the parameters that the script takes and returns, along with other metadata available from the script.
Get the id of an official script by the script path. The script service ensures that all script paths are unique.
Note: there is no similar method for user scripts (e.g. getUserScriptID) since the path is not guaranteed to be unique.
Get the text from the server for the script with given id.
Get the script from the server with details from OriginalFile Arguments:
scriptID see above
This method returns official server scripts as a list of omero.model.OriginalFile objects. These scripts will be executed by the server if submitted via runScript. The input parameters necessary for proper functioning can be retrieved via getParams.
The omero.model.OriginalFile#path value can be used in other official scripts via the language specific import command, since the script directory will be placed on the appropriate environment path variable.
scripts = scriptService.getScripts() for script in scripts: text = scriptService.getScriptText(script.id.val) path = script.path.val[1:] # First symbol is a “/” path = path.replace(“/”,”.”) print “Possible import: %s” % path
Returns non-official scripts which have been uploaded by individual users. These scripts will not be run by the server, though a user can start a personal “”usermode processor”” which will allow the scripts to be executed. This is particularly useful for testing new scripts.
If ResourceError is thrown, then no Processor is available. Use scheduleJob to create a omero.model.ScriptJob in the “Waiting” state. A Processor may become available.
try: proc = scriptService.runScript(1, {}, None) except ResourceError: job = scriptService.scheduleScript(1, {}, None)
The ScriptProcess proxy MUST be closed before exiting. If you would like the script execution to continue in the background, pass “True” as the argument.
try: proc.poll() # See if process is finished finally: proc.close(True) # Detach and execution can continue # proc.close(False) # OR script is immediately stopped.
Like uploadScript but is only callable by administrators. The parameters for the script are also checked.
Upload a user script to the server and return the id. This method checks that a script with that names does not exist and that the script has parameters if possible, i.e. a usermode processor is running which for the current user.
Used internally by processor.py to check if the script attached to the omero.model.Job has a valid script attached, based on the acceptsList and the current security context.
An example of an acceptsList might be Experimenter(myUserId, False), meaning that only scripts belonging to me should be trusted. An empty list implies that the server should return what it would by default trust.
A valid script will be returned if it exists; otherwise null.

omero.model.Session creation service for OMERO. Access to all other services is dependent upon a properly created and still active omero.model.Session.
The session uuid (omero.model.Session#getUuid) can be considered a capability token, or temporary single use password. Simply by possessing it the client has access to all information available to the omero.model.Session.
Note: Both the RMI ome.system.ServiceFactory as well as the Ice omero.api.ServiceFactory use omero.api.ISession to acquire a omero.model.Session. In the Ice case, Glacier2 contacts omero.api.ISession itself and returns a ServiceFactory remote proxy. From both ServiceFactory instances, it is possible but not necessary to access omero.api.ISession.
Closes session and releases all resources. It is preferred that all clients call this method as soon as possible to free memory, but it is possible to not call close, and rejoin a session later.
The current reference count for the session is returned. If the session does not exist, -1. If this call caused the death of the session, then -2.
Allows an admin to create a Session for the give omero.sys.Principal.
Non-null omero.sys.Principal with the target user’s name
timeToLiveMilliseconds
The time that this omero.model.Session has until destruction. This is useful to override the server default so that an initial delay before the user is given the token will not be construed as idle time. A value less than 1 will cause the default max timeToLive to be used; but timeToIdle will be disabled.
Allows an admin to create a omero.model.Session for the given omero.sys.Principal.
Non-null omero.sys.Principal with the target user’s name
timeToLiveMilliseconds
The time that this omero.model.Session has until destruction. Setting the value to 0 will prevent destruction unless the session remains idle.
timeToIdleMilliseconds
The time that this omero.model.Session can remain idle before being destroyed. Setting the value to 0 will prevent idleness based destruction.
Creates a new session and returns it to the user.
Allows a user to open up another session for him/herself with the given defaults without needing to re-enter password.

Service for the querying of OMERO metadata based on creation and modification time. Currently supported types for querying include:
The map return values will be indexed by the short type name above: “”Project”, “”Image””, ... All keys which are passed in the StringSet argument will be included in the returned map, even if they have no values. A default value of 0 or the empty list [] will be used. The only exception to this rule is that the null or empty StringSet implies all valid keys.
All methods take a omero::sys::Parameters object and will apply the filter object for paging through the data in order to prevent loading too many objects. If the parameters argument is null or no paging is activated, then the default will be: OFFSET=0, LIMIT=50. Filter.ownerId and Filter.groupId will also be AND’ed to the query if either value is present. If both are null, then the current user id will be used. To retrieve for all users, use ownerId == rlong(-1) and groupId == null.
The methods which take a StringSet and a Parameters object, also have a “”bool merge”” argument. This argument defines whether or not the LIMIT applies to each object independently ([“a”,”b”] @ 100 == 200) or merges the lists together chronologically ([“a”,”b”] @ 100 merged == 100).
Except for Image, IObject.details.updateEvent is used in all cases for determining most recent events. Images are compared via Image.acquisitionDate which is unlike the other properties is modifiable by the user.
A typical invocation might look like (in Python):
timeline = sf.getTimelineService() params = ParametersI().page(0,100) types = [“Project”,”Dataset”]) map = timeline.getByPeriod(types, params, False)
At this point, map will not contain more than 200 objects.
This service is defined only in Blitz and so no javadoc is available in the ome.api package.
TODOS: binning, stateful caching, ...
Queries the same information as getByPeriod, but only returns the counts for the given objects.
Returns the given LIMIT objects of TYPES as ordered by creation/modification times in the Event table, but within the given time window.
Returns the EventLog table objects which are queried to produce the counts above. Note the concept of “”period inclusion”” mentioned above.
WORKAROUND WARNING: this method returns non-managed EventLogs (i.e. eventLog.getId() == null) for “Image acquisitions”.
Return the last LIMIT annotation __Links__ whose parent (IAnnotated) matches one of the parentTypes, whose child (Annotation) matches one of the childTypes (limit of one for the moment), and who namespace matches via ILIKE.
The parents and children will be unloaded. The link will have its creation/update events loaded.
If Parameters.theFilter.ownerId or groupId are set, they will be AND’ed to the query to filter results.
Merges by default based on parentType.
Returns the last LIMIT objects of TYPES as ordered by creation/modification times in the Event table.
Return the last LIMIT comment annotation links attached to a share by __others__.

Binary data provider. Initialized with the ID of a omero.model.Pixels instance, this service can provide various slices, stacks, regions of the 5-dimensional (X-Y planes with multiple Z-sections and Channels over Time). The byte array returned by the getter methods and passed to the setter methods can and will be interpreted according to results of getByteWidth(), isFloat(), and isSigned().
Read-only caveat:
Mutating methods (set*) are only available during the first access. Once the Pixels data has been successfully saved (via the save or close methods on this interface), then the data should be treated read-only. If Pixels data writing fails and the service is inadvertently closed, delete the Pixels object, and create a new one. Any partially written data will be removed.

Returns a list of string ids for currently active services. This will _not_ keep services alive, and in fact checks for all expired services and removes them.
Marks the session for closure rather than detachment, which will be triggered by the destruction of the Glacier2 connection via router.destroySession()
Closing the session rather the detaching is more secure, since all resources are removed from the server and can safely be set once it is clear that a client is finished with those resources.
Allows looking up any stateful service by name.
See Constants.ice for examples of services. If a service has been added by third-parties, createByName can be used even though no concrete method is available.
Marks the session for detachment rather than closure, which will be triggered by the destruction of the Glacier2 connection via router.destroySession()
This is the default and allows a lost session to be reconnected, at a slight security cost since the session will persist longer and can be used by others if the UUID is intercepted.

Provides a list of all valid security contexts for this session. Each of the returned omero.model.IObject instances can be passed to setSecurityContext.
Returns true if the given service is alive.
Except for fatal server or session errors, this method should never throw an exception.
Requests that the given services be marked as alive. It is possible that one of the services has already timed out, in which case the returned long value will be non-zero.
Specifically, the bit representing the 0-based index will be 1:
if (retval & 1<<idx == 1<<idx) { // not alive }
Except for fatal server or session errors, this method should never throw an exception.
Sets the single callback used by the ServiceFactory to communicate with the client application. A default callback is set by the omero::client object on session creation which should suffice for most usage.
See the client object’s documentation in each language mapping for ways to use the callback.
Changes the security context for the current session.
A security context limits the set of objects which will
be returned by all queries and restricts what updates can be made.
Current valid values for security context:
omero.model.ExperimenterGroup - logs into a specific group omero.model.Share - uses IShare to activate a share
Passing an unloaded version of either object type will change
the way the current session operates. Note: only objects which are returned by the getSecurityContexts method are considered valid. Any other instance will cause an exception to be thrown.
Example usage in Python:
sf = client.createSession() objs = sf.getSecurityContexts() old = sf.setSecurityContext(objs[-1])
Re-validates the password for the current session. This prevents

Service marker for stateful services which permits the closing of a particular service before the destruction of the session.
Load a service implementation from disk if it was previously passivated. It is unnecessary to call this method since activation happens automatically, but calling this may prevent a short lapse when the service is first accessed after passivation.
It is safe to call this method at any time, even when the service is not passivated.
Frees all resources – passivated or active – for the given stateful service and removes its name from the object adapter. Any further method calls will fail with a Ice::NoSuchObjectException.
Note: with JavaEE, the close method was called publically, and internally this called destroy(). As of the OmeroBlitz migration, this functionality has been combined.
To free clients from tracking the mapping from session to stateful service, each stateful service can returns its own context information.
Causes the blitz server to store the service implementation to disk to free memory. This is typically done automatically by the server when a pre-defined memory limit is reached, but can be used by the client if it clear that a stateful service will not be used for some time.
Activation will happen automatically whether passivation was done manually or automatically.
