Class SuspiciousGetterSetterUse

  • All Implemented Interfaces:
    edu.umd.cs.findbugs.Detector, edu.umd.cs.findbugs.Priorities, edu.umd.cs.findbugs.visitclass.Constants2, org.apache.bcel.classfile.Visitor, org.apache.bcel.Constants

    public class SuspiciousGetterSetterUse
    extends edu.umd.cs.findbugs.BytecodeScanningDetector
    looks for methods that set a setter with the value obtained from the same bean's complimentary getter. This is usually a typo.
