Enclosing class:

TuringMachine

public static class TuringMachine.Transition
extends FSM.State

This class handles the Turing Machine transitions. Turing Machine transitions are a little more complicated than finite state machine transitions since tape direction and write symbols need to be accounted for.

Field Summary

protected FSM.State	nextState The next state.
protected int	tapeDirection The new tape direction.
protected int	writeSymbol The write symbol.

Constructor Summary

TuringMachine.Transition(FSM.State state, int write, int tape)
The default constructor that specifies the next state, the write symbol and tape direction.

Field Detail

nextState

protected FSM.State nextState

The next state.

writeSymbol

protected int writeSymbol

The write symbol.

tapeDirection

protected int tapeDirection

The new tape direction.

Constructor Detail

TuringMachine.Transition

public TuringMachine.Transition(FSM.State state,
                                int write,
                                int tape)

The default constructor that specifies the next state, the write symbol and tape direction. Note that the state self-sets its position according to the position of the next state.

Parameters:

state - the next state.

write - the write symbol.

tape - the tape direction.
