Class CrossLanguageMethodTargetSelector

java.lang.Object
  com.ibm.wala.cast.ipa.callgraph.CrossLanguageMethodTargetSelector

All Implemented Interfaces:

MethodTargetSelector

public class CrossLanguageMethodTargetSelector
extends java.lang.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.

Method Summary

IMethod	getCalleeTarget(CGNode caller, CallSiteReference site, IClass receiver) Given a calling node, a call site and (optionally) a dispatch type, return the target method to be called.
boolean	mightReturnSyntheticMethod(CGNode caller, CallSiteReference site) TODO: make this go away? an unnecessary optimization?
boolean	mightReturnSyntheticMethod(MethodReference declaredTarget) * TODO: make this go away? an unnecessary optimization?

Method Detail

getCalleeTarget

public IMethod getCalleeTarget(CGNode caller,
                               CallSiteReference site,
                               IClass receiver)

Description copied from interface: MethodTargetSelector

Given a calling node, a call site and (optionally) a dispatch type, return the target method to be called.

Specified by:

getCalleeTarget in interface MethodTargetSelector

Parameters:

caller - the GCNode in the call graph containing the call

site - the call site reference of the call site

receiver - the type of the target object or null

Returns:

the method to be called.

mightReturnSyntheticMethod

public boolean mightReturnSyntheticMethod(CGNode caller,
                                          CallSiteReference site)

Description copied from interface: MethodTargetSelector

TODO: make this go away? an unnecessary optimization?

Specified by:

mightReturnSyntheticMethod in interface MethodTargetSelector

Returns:

true if there's a possibility that getCalleeTarget here might return a synthetic method.

mightReturnSyntheticMethod

public boolean mightReturnSyntheticMethod(MethodReference declaredTarget)

Description copied from interface: MethodTargetSelector

* TODO: make this go away? an unnecessary optimization?

Specified by:

mightReturnSyntheticMethod in interface MethodTargetSelector

Returns:

true if there's a possibility that getCalleeTarget here might return a synthetic method.
