Class TrainUnconditionalDerefParams

java.lang.Object
  edu.umd.cs.findbugs.detect.BuildUnconditionalParamDerefDatabase
      edu.umd.cs.findbugs.detect.TrainUnconditionalDerefParams

All Implemented Interfaces:

Detector, Priorities, TrainingDetector

public class TrainUnconditionalDerefParams
extends BuildUnconditionalParamDerefDatabase
implements Detector, TrainingDetector

Training pass to find method parameters which are unconditionally dereferenced. We do this by performing a backwards dataflow analysis which sees which params are dereferenced on all non-implicit-exception paths from the CFG entry.
