Class JavaScriptFunctionApplyTargetSelector

java.lang.Object

com.ibm.wala.cast.js.ipa.callgraph.JavaScriptFunctionApplyTargetSelector

All Implemented Interfaces:

MethodTargetSelector

public class JavaScriptFunctionApplyTargetSelector
extends Object
implements MethodTargetSelector

We need to generate synthetic methods for Function.apply() in the target selector, so that the AstMethod for Function_prototype_apply() in the prologue doesn't actually get used in the CGNodes used for calls to Function.prototype.apply(). The generated dummy methods should never actually be used except as a stub.
