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

Overrides:

isEmpty in class AbstractCompoundSelectable

Returns:

true if the selectable does not provide any descriptions.

hasResourceDescription

public boolean hasResourceDescription(org.eclipse.emf.common.util.URI uri)

Specified by:

hasResourceDescription in interface IContainer

Overrides:

hasResourceDescription in class AbstractContainer

Returns:

true if the container can provide a resource description with the given uri.

getResourceDescriptionCount

public int getResourceDescriptionCount()

Specified by:

getResourceDescriptionCount in interface IContainer

Overrides:

getResourceDescriptionCount in class AbstractContainer

Returns:

the total number of resource descriptions returned by IContainer.getResourceDescriptions()

getResourceDescriptions

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

Returns:

the IResourceDescription contained in this container. The result is never null. The result may be a cached view on the actual content of the underlying resources.

getExportedObjects

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

Specified by:

getExportedObjects in interface ISelectable

Overrides:

getExportedObjects in class AbstractCompoundSelectable

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

Overrides:

getExportedObjectsByType in class AbstractCompoundSelectable

Returns:

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

getResourceDescription

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

Specified by:

getResourceDescription in interface IContainer

Overrides:

getResourceDescription in class AbstractContainer

Returns:

the IResourceDescription for the given URI, or null is this container does not contain such an IResourceDescription. The result may be a cached view on the actual content of the underlying resource.
