Package org.eclipse.xtext.scoping.impl

Class MultimapBasedScope

java.lang.Object

org.eclipse.xtext.scoping.impl.AbstractScope

org.eclipse.xtext.scoping.impl.MultimapBasedScope

All Implemented Interfaces:

IScope

public class MultimapBasedScope
extends AbstractScope

A scope implemented using a Multimap. This implementation assumes, that the keys of the Multimap are the keys of the contained EObjectDescriptions as well as the name. When looking up elements using AbstractScope.getElements(QualifiedName) this implementation looks up the elements from the map, hence are much more efficient for many IEObjectDescriptions.
