All Implemented Interfaces:

InstanceKeyFactory

public class CrossLanguageInstanceKeys
extends java.lang.Object
implements InstanceKeyFactory

An InstanceKeyFactory implementation that is designed to support multiple languages. This implementation delegates to one of several child instance key factories based on the language associated with the IClass or TypeReference for which an instance key is being chosen.
