Constructor Detail

LayeredTypeResourceDescription

public LayeredTypeResourceDescription(TypeResourceDescription delegate,
                                      java.util.List<IEObjectDescription> additionallyExported)

Method Detail

getImportedNames

public java.lang.Iterable<QualifiedName> getImportedNames()

Specified by:

getImportedNames in interface IResourceDescription

Returns:

the list of names the described resource depends depends on.

getReferenceDescriptions

public java.lang.Iterable<IReferenceDescription> getReferenceDescriptions()

Specified by:

getReferenceDescriptions in interface IResourceDescription

Returns:

the list of all references contained in the underlying resource.

getURI

public org.eclipse.emf.common.util.URI getURI()

Specified by:

getURI in interface IResourceDescription

Returns:

the uri of the described resource. Will not return null.

getExportedObjects

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

Specified by:

getExportedObjects in interface IResourceDescription

Specified by:

getExportedObjects in interface ISelectable

Returns:

descriptions of all EObjects provided by the given Resource. The result is expected to return any combination of name and eObjectOrProxy only once as an IEObjectDescription. The order of the exported objects matters.

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 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)

Specified by:

getExportedObjectsByObject in interface ISelectable

Returns:

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

getExportedObjects

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

Specified by:

getExportedObjects in interface ISelectable

Returns:

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