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

See Also:

• OpcodeStackDetector.beforeOpcode(int)

visitAfter

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

Description copied from class: PreorderVisitor

Called after visiting a code attribute

Overrides:

visitAfter in class PreorderVisitor

Parameters:

obj - Code that was just visited

runDateFormatRuleVerify

private boolean runDateFormatRuleVerify(String dateFormat)

Runs the check per each bad combination (Rule objects) on the provided string.

Parameters:

dateFormat - - string to be checked

Returns:

true if given string matches any bad combination.

removeNonInterpretedText

protected String removeNonInterpretedText(String dateFormat)
