Method Details

sawOpcode

public void sawOpcode(int seen)

Description copied from class: OpcodeStackDetector

By default, this method will not be called when stack is TOP. To change this behavior, override #beforeOpcode(int) and change to return true even if stack is TOP.

see Using FindBugs for Research to learn lattice and what TOP means.

Specified by:

sawOpcode in class OpcodeStackDetector

• OpcodeStackDetector.beforeOpcode(int)

visitAfter

public void visitAfter(org.apache.bcel.classfile.JavaClass obj)

Overrides:

visitAfter in class PreorderVisitor

visit

public void visit(org.apache.bcel.classfile.JavaClass obj)

Overrides:

visit in class BetterVisitor
