Interface PositionForInterpretation

All Superinterfaces:
Position
public interface PositionForInterpretation extends Position
An interface to a tuple position for interpretation.

This is differentiated from a position interface for compilation because compilation requires linear access (i.e., non-jumps) to the tuple list, while interpretation requires this as well as jump capability.

  • Method Details

    • jump

      void jump(Address address)
      Reposition to the tuple located at a particular address. This is usually done in a response to an if condition. However, this is also done to perform loops, etc.
      Parameters:
      address - The target address for the jump.

    • current

      int current()

      current.

      Returns:
      The current index into the tuple list (queue) of the tuple located at the current position.

    • jump

      void jump(int idx)
      Reposition to the tuple located at a particular index into the tuple list (queue)..
      Parameters:
      idx - The target index for the jump.
