      Modifier and Type Method Description
      void branch​(Clazz clazz, CodeAttribute codeAttribute, int offset, int branchTarget)
      Sets the new instruction offset.
      void branchConditionally​(Clazz clazz, CodeAttribute codeAttribute, int offset, int branchTarget, int conditional)
      Sets the new instruction offset, depending on the certainty of the conditional branch.
      InstructionOffsetValue getTraceBranchTargets()
      Returns the accumulated branch targets that were passed to the branch unit methods.
      void reset()
      Resets the accumulated branch targets and the flag that tells whether any of the branch unit methods was called.
      void returnFromMethod()
      Returns from the method with the given value.
      void throwException()
      Handles the throwing of an exception.
      boolean wasCalled()
      Returns whether any of the branch unit methods was called.
