      toString in class Instruction
      Parameters:
      verbose - long/short format switch
      Returns:
      mnemonic for instruction

    • initFromFile

      protected void initFromFile(ByteSequence bytes, boolean wide) throws IOException
      Read needed data (e.g. index) from file.
      Overrides:
      initFromFile in class Instruction
      Parameters:
      bytes - byte sequence to read from
      wide - "wide" instruction flag
      Throws:

    • getExceptions

      public Class<?>[] getExceptions()
      Specified by:
      getExceptions in interface ExceptionThrower

    • 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
