Returns:

the definition of this automata.

              throws NoTransitionFoundException

Sends a character to this automata.

Parameters:

character - The character to be sent to this automata.

Throws:

NoTransitionFoundException

getTransitionFor

public Transition getTransitionFor(char character)

Returns the transition that can be activated from this automata's current state with the specified character.

Returns:

The current state of this automata.

getReceivedCharacters
