Constructor Detail

FormExtContext

public FormExtContext(long bmObjectId,
                      org.eclipse.emf.ecore.EClass eClass,
                      String segmentId,
                      boolean removal,
                      Object computationCause,
                      long baseVersion)

Constructs an instance of the context

Parameters:

bmObjectId - The identifier of the top object

eClass - The EClass of the top object. May not be null

segmentId - The DD segment. May not be null

removal - True if the context is a removal context

computationCause - Initial computation cause (like change even of the BM, etc)

baseVersion - The base version of the context

Method Detail

addFeatures

public void addFeatures(Collection<org.eclipse.emf.ecore.EStructuralFeature> features)

Adds features that are being changed as a result of external model change

Parameters:

features - The feature collection to add. May not be null

getFeatures

public Set<org.eclipse.emf.ecore.EStructuralFeature> getFeatures()

Gets changed features

Returns:

The set of features which values were changed as the result of a model change

clearExtendedData

protected void clearExtendedData()

Description copied from class: PartBasedObjectContext

Cleans extended data of the context on full rebuild to free the resources

Overrides:

clearExtendedData in class PartBasedObjectContext

copyExtendedDataForContainments

protected void copyExtendedDataForContainments(PartBasedContainmentContext sourceContext,
                                               PartBasedContainmentContext destinationContext)

Description copied from class: PartBasedObjectContext

Copies extended data of the containment context

Overrides:

copyExtendedDataForContainments in class PartBasedObjectContext

Parameters:

sourceContext - Source context to copy data from. May not be null

destinationContext - Destination context to copy data to. May not be null

createPartBasedContainmentContext

protected PartBasedContainmentContext createPartBasedContainmentContext(long bmObjectId)

Description copied from class: PartBasedObjectContext

Creates a corresponding part-based containment context. May be used to customize containment contexts in client applications

Overrides:

createPartBasedContainmentContext in class PartBasedObjectContext

Parameters:

bmObjectId - The BM object identifier to get context for.

Returns:

The context. May not be null

createTopObjectContextSnapshot

protected PartBasedObjectContext createTopObjectContextSnapshot()

Description copied from class: PartBasedObjectContext

Creates snapshot instance of the current context. Do not create snapshot of containments within this method, only data of the top object context itself must be copied

Overrides:

createTopObjectContextSnapshot in class PartBasedObjectContext

Returns:

The snapshot instance of the current context. May not be null

mergeContainmentExtendedDataUpdates

protected boolean mergeContainmentExtendedDataUpdates(PartBasedContainmentContext sourceContext,
                                                      PartBasedContainmentContext destinationContext)

Description copied from class: PartBasedObjectContext

TODO JavaDoc

Overrides:

mergeContainmentExtendedDataUpdates in class PartBasedObjectContext

Returns:

mergeExtendedDataUpdates

protected boolean mergeExtendedDataUpdates(IObjectDerivedDataContext context)

Description copied from class: PartBasedObjectContext

Merges extended data updates.

Overrides:

mergeExtendedDataUpdates in class PartBasedObjectContext

Parameters:

context - The context to get data from. May not be null

Returns:

True if changes were made during the merge of the extended updates
