Method Summary

Modifier and Type	Method and Description
Transition<java.util.function.Supplier<java.util.stream.Stream<T>>,T>	apply(java.util.function.Supplier<java.util.stream.Stream<T>> state, T item) Apply the given input to the given state, returning a transition to a new state with 0 or more outputs.
java.util.stream.Stream<T>	finish(java.util.function.Supplier<java.util.stream.Stream<T>> finalState) Based on the final state (if non-terminal), obtain any "left-over" outputs when the end of the stream is reached.
java.util.function.Supplier<java.util.stream.Stream<T>>	getInitialState()
boolean	isTerminal(java.util.function.Supplier<java.util.stream.Stream<T>> state) Test whether a given state is terminal and stream traversal should stop.

Method Detail

apply

public Transition<java.util.function.Supplier<java.util.stream.Stream<T>>,T> apply(java.util.function.Supplier<java.util.stream.Stream<T>> state,
                                                                                   T item)

Description copied from interface: StateMachine

Apply the given input to the given state, returning a transition to a new state with 0 or more outputs.

Specified by:

apply in interface StateMachine<java.util.function.Supplier<java.util.stream.Stream<T>>,T,T>

Parameters:

state - The state to transition from.

item - The input to apply to the state.

Returns:

The transition.

isTerminal

public boolean isTerminal(java.util.function.Supplier<java.util.stream.Stream<T>> state)

Description copied from interface: StateMachine

Test whether a given state is terminal and stream traversal should stop.

Specified by:

isTerminal in interface StateMachine<java.util.function.Supplier<java.util.stream.Stream<T>>,T,T>

Parameters:

state - The state to test.

Returns:

True if the state is terminal, false otherwise.

finish

public java.util.stream.Stream<T> finish(java.util.function.Supplier<java.util.stream.Stream<T>> finalState)

Description copied from interface: StateMachine

Based on the final state (if non-terminal), obtain any "left-over" outputs when the end of the stream is reached.

Specified by:

finish in interface StateMachine<java.util.function.Supplier<java.util.stream.Stream<T>>,T,T>

Parameters:

finalState - The state at the end of the stream.

Returns:

The final outputs from the state machine.

getInitialState

public java.util.function.Supplier<java.util.stream.Stream<T>> getInitialState()

Specified by:

getInitialState in interface StateMachine<java.util.function.Supplier<java.util.stream.Stream<T>>,T,T>
