Constructor Details

BslObjectReferencePersistenceContributor

@Inject
public BslObjectReferencePersistenceContributor(String extension)

Constructs a new instance.

Parameters:

extension - The supported file extension. May not be null.

Method Details

createReferenceValue

public Object createReferenceValue(org.eclipse.emf.ecore.EObject target,
 IBmNamespace contextNs)

Description copied from interface: IBmReferencePersistenceContributor

Creates internal representation of reference value.

Specified by:

createReferenceValue in interface IBmReferencePersistenceContributor

Parameters:

target - The object (may be a proxy) the reference points to (reference target). May not be null.

contextNs - The context namespace, i.e. the namespace the referencing object belongs to. May not be null.

Returns:

the internal representation of the reference value or null if the target object is not supported by this contributor or reference to the target object may not be created. The class of the returned object must implement equals method so that it returns true in case either reference value points to the same target.

resolveTarget

public org.eclipse.emf.ecore.EObject resolveTarget(Object value,
 IBmNamespace contextNs,
 IBmPlatformTransaction transaction)

Description copied from interface: IBmReferencePersistenceContributor

Resolves target object pointed by the specified reference value. In case the provided value has not been created by this contributor the behaviour of this method is not specified.

Specified by:

resolveTarget in interface IBmReferencePersistenceContributor

Parameters:

value - The reference value. May not be null.

contextNs - The context namespace, i.e. the namespace the referencing object belongs to. May not be null.

transaction - The current transaction. May not be null.

Returns:

the target object or null if it does not exist.

resolveTargetUri

public org.eclipse.emf.common.util.URI resolveTargetUri(Object value,
 IBmNamespace contextNs)

Description copied from interface: IBmReferencePersistenceContributor

Resolves URI of the target object pointed by the specified reference value. In case the provided value has not been created by this contributor the behaviour of this method is not specified.

Specified by:

resolveTargetUri in interface IBmReferencePersistenceContributor

Parameters:

value - The reference value. May not be null.

contextNs - The context namespace, i.e. the namespace the referencing object belongs to. May not be null.

Returns:

the URI of the target object, never null.

serializeReferenceValue

public void serializeReferenceValue(Object value,
 DataOutput output)
                             throws IOException

Description copied from interface: IBmReferencePersistenceContributor

Serializes the specified reference value. In case the provided value has not been created by this contributor the behaviour of this method is not specified.

Specified by:

serializeReferenceValue in interface IBmReferencePersistenceContributor

Parameters:

value - The reference value to serialize. May not be null.

output - The data output to write the serialized representation to. May not be null.

Throws:

IOException

deserializeReferenceValue

public Object deserializeReferenceValue(DataInput input)
                                 throws IOException

Description copied from interface: IBmReferencePersistenceContributor

Deserializes reference value. In case data supplied by the specified input are corrupt the behaviour of this method is not specified.

Specified by:

deserializeReferenceValue in interface IBmReferencePersistenceContributor

Parameters:

input - The data input to read the serialized representation from. May not be null.

Returns:

the deserialized reference value, never null.

Throws:

IOException

getId

public String getId()

Description copied from interface: IBmReferencePersistenceContributor

Gets ID of the contributor. The ID must not change after the application restart. It is convenient to use the class name of the contributor as the ID unless several instances of the same contributor class are bound to the same engine.

Specified by:

getId in interface IBmReferencePersistenceContributor

Returns:

the ID of the contributor.
