构造器详细资料

AbstractTransition

public AbstractTransition(java.lang.Object eventId)

Creates a new instance which will loopback to the same State for the specified Event id.

参数:

eventId - the Event id.

AbstractTransition

public AbstractTransition(java.lang.Object eventId,
                  State nextState)

Creates a new instance with the specified State as next state and for the specified Event id.

参数:

eventId - the Event id.

nextState - the next State.

方法详细资料

getNextState

public State getNextState()

指定者:

getNextState 在接口中 Transition

返回:

the State which the StateMachine should move to if this Transition is taken and Transition.execute(Event) returns true. null if this Transition is a loopback Transition.

execute

public boolean execute(Event event)

从接口复制的说明: Transition

Executes this Transition. It is the responsibility of this Transition to determine whether it actually applies for the specified Event. If this Transition doesn't apply nothing should be executed and false must be returned.

指定者:

execute 在接口中 Transition

参数:

event - the current Event.

返回:

true if the Transition was executed, false otherwise.

doExecute

protected abstract boolean doExecute(Event event)

Executes this Transition. This method doesn't have to check if the Event's id matches because execute(Event) has already made sure that that is the case.

参数:

event - the current Event.

返回:

true if the Transition has been executed successfully and the StateMachine should move to the next State. false otherwise.

equals

public boolean equals(java.lang.Object o)

覆盖:

equals 在类中 java.lang.Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 java.lang.Object

toString

覆盖:

toString 在类中 java.lang.Object
