  • Method Details

    • isEOF

      boolean isEOF()

      isEOF.

      Returns:
      true whether we are at the end of the tuple list, false otherwise

    • next

      void next()
      Advances the position to the next tuple, as ordered within the tuple list (queue).

    • opcode

      int opcode()

      opcode.

      Returns:
      the opcode for the tuple at this position

    • intArg

      long intArg(int idx)
      Get the integer representation for a particular element within the tuple.
      Parameters:
      idx - The item to retrieve from the tuple.
      Returns:
      the integer representation of the item.

    • boolArg

      boolean boolArg(int idx)
      Get the boolean representation for a particular element within the tuple.
      Parameters:
      idx - The item to retrieve from the tuple.
      Returns:
      the boolean representation of the item.

    • arg

      Get a reference to a particular element within the tuple.
      Parameters:
      idx - The item to retrieve from the tuple.
      Returns:
      a reference to the item.

    • addressArg

      Address addressArg()
      Obtain the address argument for this tuple.

      This is a special form in that the tuple has only the address argument, and nothing else.

      Returns:
      a Address object

    • classArg

      Class<?> classArg()
      Obtain the class argument for this tuple.

      This is a special form in that the tuple has only the class argument, and nothing else.

      Returns:
      a Class object

    • lineNumber

      int lineNumber()
      Get the source line number for this position.
      Returns:
      a int
