类 StateMachine

java.lang.Object

org.apache.mina.statemachine.StateMachine

public class StateMachine
extends java.lang.Object

Represents a complete state machine. Contains a collection of State objects connected by Transitions. Normally you wouldn't create instances of this class directly but rather use the State annotation to define your states and then let StateMachineFactory create a StateMachine for you.

构造器详细资料

StateMachine

public StateMachine(State[] states,
            java.lang.String startStateId)

Creates a new instance using the specified States and start state.

参数:

states - the States.

startStateId - the id of the start State.

StateMachine

public StateMachine(java.util.Collection<State> states,
            java.lang.String startStateId)

Creates a new instance using the specified States and start state.

参数:

states - the States.

startStateId - the id of the start State.

方法详细资料

getState

public State getState(java.lang.String id)
               throws NoSuchStateException

Returns the State with the specified id.

参数:

id - the id of the State to return.

返回:

the State

抛出:

NoSuchStateException - if no matching State could be found.

getStates

public java.util.Collection<State> getStates()

返回:

an unmodifiable Collection of all States used by this StateMachine.

handle

public void handle(Event event)

Processes the specified Event through this StateMachine. Normally you wouldn't call this directly but rather use StateMachineProxyBuilder to create a proxy for an interface of your choice. Any method calls on the proxy will be translated into Event objects and then fed to the StateMachine by the proxy using this method.

参数:

event - the Event to be handled.
