Method Detail

isEmpty

public boolean isEmpty()

Description copied from interface: ISelectable

Clients may want to check the selectable to skip its processing in case it is empty. Implementations should be fast and not require expensive precalculation. Selectable may return false if it is too expensive to compute the actual result.

Specified by:

isEmpty in interface ISelectable

Returns:

true if the selectable does not provide any descriptions.

getExportedObjectsByType

public Iterable<IEObjectDescription> getExportedObjectsByType(org.eclipse.emf.ecore.EClass type)

Specified by:

getExportedObjectsByType in interface ISelectable

Returns:

all elements which match the given type. May not be null.

getExportedObjectsByObject

public Iterable<IEObjectDescription> getExportedObjectsByObject(org.eclipse.emf.ecore.EObject object)

Specified by:

getExportedObjectsByObject in interface ISelectable

Returns:

all elements which match the given instance. May not be null.

public Iterable<IEObjectDescription> getExportedObjects(org.eclipse.emf.ecore.EClass type,
                                               QualifiedName name,
                                               boolean ignoreCase)

Specified by:

getExportedObjects in interface ISelectable
