Method Detail

addTransition

public FiniteStateMachine.Builder<T> addTransition(T startState,
                                                   T endState)

Add a legal transition to the FiniteStateMachine.

addUniversalEnd

public FiniteStateMachine.Builder<T> addUniversalEnd(T state)

Specify that a state is a valid end state for a transition starting from any state. Useful for example for error states.

errorState

public FiniteStateMachine.Builder<T> errorState(T state)

Specify the error state to which this machine can transition if nothing else is possible. Note the error state is always an allowed end state.

build

public FiniteStateMachine<T> build(T initialState)

Build a FiniteStateMachine starting at the given initial state.
