Method Details

visitClassContext

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

getClassContext

public ClassContext getClassContext()

Get the ClassContext of the class currently being visited.

Returns:

the current ClassContext

shouldVisitCode

public boolean shouldVisitCode(org.apache.bcel.classfile.Code obj)

Check see if the Code for this method should be visited.

Parameters:

obj - Code attribute

Returns:

true if the Code should be visited

report

public void report()

Description copied from interface: Detector
