    • Constructor Detail

      • JSR

        JSR()
        Empty constructor needed for Instruction.readInstruction. Not to be used otherwise.
    • Method Detail

      • accept

        public void accept​(Visitor v)
        Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, i.e., the most specific visitXXX() call comes last.
        Specified by:
        accept in class Instruction
        Parameters:
        v - Visitor object
      • dump

        public void dump​(java.io.DataOutputStream out)
                  throws java.io.IOException
        Dump instruction as byte code to stream out.
        Overrides:
        dump in class BranchInstruction
        Parameters:
        out - Output stream
        Throws:
        java.io.IOException - Thrown when an I/O exception of some sort has occurred.
      • updatePosition

        protected int updatePosition​(int offset,
                                     int maxOffset)
        Description copied from class: BranchInstruction
        Called by InstructionList.setPositions when setting the position for every instruction. In the presence of variable length instructions 'setPositions' performs multiple passes over the instruction list to calculate the correct (byte) positions and offsets by calling this function.
        Overrides:
        updatePosition in class BranchInstruction
        Parameters:
        offset - additional offset caused by preceding (variable length) instructions
        maxOffset - the maximum offset that may be caused by these instructions
        Returns:
        additional offset caused by possible change of this instruction's length
