Class GeomEvaluator

java.lang.Object

soot.jimple.spark.geom.helper.GeomEvaluator

public class GeomEvaluator
extends Object

We provide a set of methods to evaluate the quality of geometric points-to analysis. The evaluation methods are: 1. Count the basic points-to information, such as average points-to set size, constraints evaluation graph size, etc; 2. Virtual function resolution comparison; 3. Static casts checking; 4. All pairs alias analysis; 5. Building heap graph (not used yet).
