Class CrossLanguageMethodTargetSelector

java.lang.Object

com.ibm.wala.cast.ipa.callgraph.CrossLanguageMethodTargetSelector

All Implemented Interfaces:

MethodTargetSelector

public class CrossLanguageMethodTargetSelector
extends Object
implements MethodTargetSelector

A MethodTargetSelector implementation that supports multiple languages. It works by delegating to a language-specific child selector based on the language associated with the MethodReference for which a target is being chosen.

This provides a simple way to combine language-specific target selection policies---such as those used for constructor calls in JavaScript and for bean methods in J2EE.
