public java.lang.Iterable<IResourceDescription> getAllResourceDescriptions()
- Specified by:
getAllResourceDescriptions
in interfaceIResourceDescriptions
-
setRegistry
public void setRegistry(IResourceServiceProvider.Registry registry)
-
getResourceSet
public org.eclipse.emf.ecore.resource.ResourceSet getResourceSet()
- Specified by:

in interfaceIResourceDescriptions.IResourceSetAware
-
getSelectables
protected java.lang.Iterable<? extends ISelectable> getSelectables()
- Specified by:
getSelectables
in classAbstractCompoundSelectable
-
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 returnfalse
if it is too expensive to compute the actual result.- Specified by:
isEmpty
in interfaceISelectable
- Overrides:
isEmpty
in classAbstractCompoundSelectable
- Returns:
true
if the selectable does not provide any descriptions.

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:
