      • updateTargets

        void updateTargets()
        Use the byte indexes read from the class file to calculate and set references to the target instruction(s) for this ptr. This method will be called after the byte code has been read in for the first time and before it is written after modification.
      • replaceTarget

        void replaceTarget​(Instruction oldTarget,
                           Instruction newTarget)
        Replace the given old, likely invalid, target with a new target. The new target Instruction is guaranteed to be in the same code block as this InstructionPtr.
      • getCode

        Code getCode()
        Returns the Code block that owns the Instruction(s) this InstructionPtr points to.
