Method Detail

getAllResourceDescriptions

public java.lang.Iterable<IResourceDescription> getAllResourceDescriptions()

Specified by:

getAllResourceDescriptions in interface IResourceDescriptions

getResourceDescription

public IResourceDescription getResourceDescription(org.eclipse.emf.common.util.URI uri)

Description copied from interface: IResourceDescriptions

Returns the resource descriptions for the given URI.

Specified by:

getResourceDescription in interface IResourceDescriptions

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.

getExportedObjects

public java.lang.Iterable<IEObjectDescription> getExportedObjects()

Specified by:

getExportedObjects in interface ISelectable

Returns:

all exported elements. May not be null.

getExportedObjects

public java.lang.Iterable<IEObjectDescription> getExportedObjects(org.eclipse.emf.ecore.EClass type,
                                                                  QualifiedName name,

Specified by:

getExportedObjects in interface ISelectable

Returns:

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

getExportedObjectsByType

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