Class PermDetails

java.lang.Object

ome.util.PermDetails

All Implemented Interfaces:

java.io.Serializable, IObject, Filterable

public class PermDetails
extends java.lang.Object
implements IObject

wrapper class which can be used in HQL queries to properly load the full context for a permissions object. Rather than writing a query of the form: select d.details.permissions from Dataset d which returns a Permissions object with none of the extended restrictions (canRead, canAnnotate, etc) properly loaded, use: select new ome.util.PermDetails(d) from Dataset d The return value for each will be the same.

Constructor Detail

PermDetails

public PermDetails(IObject context)

Method Detail

getInternalContext

public IObject getInternalContext()

In order to properly test the permissions for this object, it must be possible to get the internal context. This is for use by the security system only.

getId

public java.lang.Long getId()

Description copied from interface: IObject

primary key of this object. Before the session is flushed, this value may be null.

Specified by:

getId in interface IObject

Returns:

Long primary key. May be null.

setId

public void setId(java.lang.Long id)

Description copied from interface: IObject

usually unneeded. Ids are managed by the backend.

Specified by:

setId in interface IObject

Parameters:

id - Long value for this id.

getDetails

public Details getDetails()

Description copied from interface: IObject

Value (i.e. not entity) which is available on all rows in the database. Low-level "details" such as security, ownership, auditing are managed here. When setting values on Details, it is important to realize that most of the values are managed by the backend and may be replaced. For example, a user does not have permission to change the owner of an object, not even when owned by that user. To replace all of the values from an existing Details instance, use Details.copy(Details) or Details.shallowCopy(Details)

Specified by:

getDetails in interface IObject

isLoaded

public boolean isLoaded()

Description copied from interface: IObject

transient field (not stored in the DB) which specifies whether this object has been loaded from the DB or is only a wrapper around the ID.

Specified by:

isLoaded in interface IObject

unload

public void unload()
            throws ApiUsageException

Description copied from interface: IObject

set the loaded field to false, and set all non-ID fields to null. Subsequent calls to all accessors other than getId/setId will throw an ApiUsageException

Specified by:

unload in interface IObject

Throws:

ApiUsageException

isValid

public boolean isValid()

Description copied from interface: IObject

calls the class-specific validator for this instance and returns the value from Validation.isValid()

Specified by:

isValid in interface IObject

validate

public Validation validate()

Description copied from interface: IObject

calls the class-specific validator for this instance and returns the Validation object.

Specified by:

validate in interface IObject

Returns:

Validation collecting parameter.

retrieve

public java.lang.Object retrieve(java.lang.String field)

Description copied from interface: IObject

retrieves a value from this instance. Values for field which match a field of this instance will be delegated to the accessors. Otherwise, values will be retrieved from a lazy-loaded map filled by calls to IObject.putAt(String, Object)

Specified by:

retrieve in interface IObject

putAt

public void putAt(java.lang.String field,
                  java.lang.Object value)

Description copied from interface: IObject

stores a value in this instance. Values for field which match a field of this instance will be delegated to the accessors. Otherwise, values will be stored in a lazy-loaded map.

Specified by:

putAt in interface IObject

Parameters:

field - Field name

value - Any object to be stored.

fields

public java.util.Set<?> fields()

Description copied from interface: IObject

returns a Set of field names that belong to this class

Specified by:

fields in interface IObject

getGraphHolder

public GraphHolder getGraphHolder()

Description copied from interface: IObject

retrieves the GraphHolder for this entity. If the GraphHolder has not been actively set, a new one will be instatiated.

Specified by:

getGraphHolder in interface IObject

Returns:

Non-null GraphHolder

acceptFilter

public boolean acceptFilter(Filter filter)

Specified by:

acceptFilter in interface Filterable
