Class NaiveSideEffectTester

java.lang.Object

soot.jimple.NaiveSideEffectTester

All Implemented Interfaces:

SideEffectTester

public class NaiveSideEffectTester
extends java.lang.Object
implements SideEffectTester

Provides naive side effect information. Relies on no context information; instead, does the least conservative thing possible even in the possible presence of badness. Possible weakness of SideEffectTester: consider a Box. We don't have a name for "what-is-inside-the-box" and so we can't ask questions about it. But perhaps we need only ask questions about the box itself; the sideeffect tester can deal with that internally.
