Class CrossLanguageContextSelector

java.lang.Object

com.ibm.wala.cast.ipa.callgraph.CrossLanguageContextSelector

All Implemented Interfaces:

com.ibm.wala.ipa.callgraph.ContextSelector

public class CrossLanguageContextSelector
extends java.lang.Object
implements com.ibm.wala.ipa.callgraph.ContextSelector

A ContextSelector implementation adapted to work for analysis across multiple languages. This context selector delegates to one of several child selectors based on the language of the code body for which a context is being selected.

This provides a convenient way to integrate multiple, language-specific specialized context policies---such as the ones used for clone() in Java and runtime primitives in JavaScript.
