Specified by:

getSelectables in class AbstractCompoundSelectable

getResourceDescriptionCount

public int getResourceDescriptionCount()

Specified by:

getResourceDescriptionCount in interface IContainer

Returns:

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

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

Specified by:

hasResourceDescription in interface IContainer

Returns:

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

getResourceDescription

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