public abstract class BucketedEObjectDescription
extends org.eclipse.xtext.resource.EObjectDescription
implements IIdentifiableElementDescription

A description that contains some more information, e.g. on the bound type parameters, the receiver or its type. The bucket concept allows to properly identify ambiguous descriptions, e.g. if two descriptions from the very same bucket are matching with equal confidence, the link is ambiguous and should be indicated as such. A possible scenario is a conflict in the static imports where two imported types have the very same static method signature, e.g. main(String[]). If the client tries to invoke that method without an explicitly declared receiver, it should be flagged as ambiguous.
