Method Detail

initialize

public void initialize(IResourceDescriptions delegate,

              org.eclipse.emf.ecore.resource.Resource context)

getAllResourceDescriptions

public Iterable<IResourceDescription> getAllResourceDescriptions()

Specified by:

getAllResourceDescriptions 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

Overrides:

isEmpty in class AbstractCompoundSelectable

Returns:

true if the selectable does not provide any descriptions.

getSelectables

protected Iterable<? extends ISelectable> getSelectables()

Specified by:

getSelectables in class AbstractCompoundSelectable

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
