beforeOpcode
public boolean beforeOpcode(int seen) Description copied from class:DismantleBytecode
return false if we should skip calling sawOpcode- Overrides:
beforeOpcode
in classOpcodeStackDetector
-
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.
