Chgrp2I

public Chgrp2I(ACLVoter aclVoter,
               Roles securityRoles,
               GraphPathBean graphPathBean,
               LightAdminPrivileges adminPrivileges,

               org.springframework.context.ApplicationContext applicationContext)

Construct a new chgrp request; called from GraphRequestFactory.getRequest(Class).

Parameters:

aclVoter - ACL voter for permissions checking

securityRoles - the security roles

graphPathBean - the graph path bean to use

adminPrivileges - the light administrator privileges helper

deletionInstance - a deletion instance for deleting files

targetClasses - legal target object classes for chgrp

graphPolicy - the graph policy to apply for chgrp

unnullable - properties that, while nullable, may not be nulled by a graph traversal operation

applicationContext - the OMERO application context from Spring

Method Detail

getCallContext

public java.util.Map<java.lang.String,java.lang.String> getCallContext()

Description copied from interface: IRequest

Returns the desired call context for this request. Some request implementations will require "omero.group":"-1" for example and will hard-code that value. Others may permit users to pass in the desired values which will be merged into the static Map as desired.

Specified by:

getCallContext in interface IRequest

Returns:

the call context for this request

init

public void init(Helper helper)

Description copied from interface: IRequest

Method called within the transaction boundaries before any processing occurs. Implementations must properly initialize the "step" field of the Status object by calling Helper.setSteps(int). This count will define how many times the IRequest.step(int) method will be called. The Helper instance passed in contains those resources needed by IRequests to interact with data and should be stored for later use.

Specified by:

init in interface IRequest

Parameters:

helper - the helper for this request

step

public java.lang.Object step(int step)
                      throws HandleI.Cancel

Description copied from interface: IRequest

Single uncancellable action which will be performed by this IRequest. The return value can be an ome.model object that is attached to the current thread and transaction. After processing and detachment from the transaction, the object will be passed to IRequest.buildResponse(int, Object) for conversion and storage.

Specified by:

step in interface IRequest

Parameters:

step - the step number

Returns:

an object to be used in building the response

Throws:

HandleI.Cancel - if this request is cancelled

finish

public void finish()

Description copied from interface: IRequest

Method within the transaction boundaries after all processing has occurred. A thrown HandleI.Cancel will still rollback the current transaction.

Specified by:

finish in interface IRequest

buildResponse

public void buildResponse(int step,
                          java.lang.Object object)

Description copied from interface: IRequest

Post-transaction chance to map from the return value of IRequest.step(int) to a Response object.

Specified by:

buildResponse in interface IRequest

Parameters:

step - the step number

object - an object to be used in building the response

getResponse

public omero.cmd.Response getResponse()

Description copied from interface: IRequest

Returns the current response value. This method should be protected by synchronization where necessary, and should never raise an exception. It is also guaranteed to be called so that any state cleanup that is necessary can take place here.

Specified by:

getResponse in interface IRequest

Returns:

the response to this request

copyFieldsTo

public void copyFieldsTo(omero.cmd.Chgrp2 request)

Description copied from interface: WrappableRequest

Copy the fields of this request to that of the given request.

Specified by:

copyFieldsTo in interface WrappableRequest<omero.cmd.Chgrp2>

Parameters:

request - the target of the field copy

adjustGraphPolicy

public void adjustGraphPolicy(com.google.common.base.Function<GraphPolicy,GraphPolicy> adjuster)

Description copied from interface: WrappableRequest

Transform the currently applicable graph policy for this request by the given function. Must be called before IRequest.init(omero.cmd.Helper).

Specified by:

adjustGraphPolicy in interface WrappableRequest<omero.cmd.Chgrp2>

Parameters:

adjuster - a transformation function for graph policies

getStepProvidingCompleteResponse

public int getStepProvidingCompleteResponse()

Description copied from interface: WrappableRequest

Get the step of this request that suffices for assembling the request's response. It is presumed that checking the permissibility of the planned operation occurs afterward.

Specified by:

getStepProvidingCompleteResponse in interface WrappableRequest<omero.cmd.Chgrp2>

Returns:

a step number

getActionForStarting

public GraphPolicy.Action getActionForStarting()

Specified by:

getActionForStarting in interface WrappableRequest<omero.cmd.Chgrp2>

Returns:

the action associated with nodes qualifying as start objects

getStartFrom

public java.util.Map<java.lang.String,java.util.List<java.lang.Long>> getStartFrom(omero.cmd.Response response)

Description copied from interface: WrappableRequest

From the response of the head-skipping request, determine which model objects are the targets of the operation.

Specified by:

getStartFrom in interface WrappableRequest<omero.cmd.Chgrp2>

Parameters:

response - the head-skipping request's response

Returns:

the model objects to target

isReadOnly

public boolean isReadOnly(ReadOnlyStatus readOnly)

Specified by:

isReadOnly in interface ReadOnlyStatus.IsAware

Parameters:

readOnly - a read-only status, typically the current one

Returns:

if that status puts this class into read-only mode
