Interface CodeRelabeler
- All Superinterfaces:
ClassFileTransform<CodeTransform, CodeElement, CodeBuilder>,CodeTransform
A code relabeler is a
CodeTransform replacing all occurrences
of Label in the transformed code with new instances.
All LabelTarget instructions are adjusted accordingly.
Relabeled code graph is identical to the original.
Primary purpose of CodeRelabeler is for repeated injections of the same code blocks.
Repeated injection of the same code block must be relabeled, so each instance of
Label is bound in the target bytecode exactly once.
