public void visitClassContext(ClassContext classContext)

Description copied from interface: Detector

Visit the ClassContext for a class which should be analyzed for instances of bug patterns.

Specified by:

visitClassContext in interface Detector

Parameters:

classContext - the ClassContext

normalize

private String normalize(String condition)

getPriority

private int getPriority(MethodDescriptor methodDescriptor,
 ValueRangeAnalysisFactory.RedundantCondition condition)

getConsumer

private org.apache.bcel.generic.InstructionHandle getConsumer(org.apache.bcel.generic.MethodGen methodGen,
 org.apache.bcel.generic.InstructionHandle start)

Parameters:

methodGen - method

start - instruction to scan

Returns:

instruction which consumes value which was on top of stack before start instruction or null if cannot be determined
