org.apache.mina.statemachine.State

public class State
extends java.lang.Object

Represents a state in a StateMachine. 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.

States inherits Transitions from their parent. A State can override any of the parents Transitions. When an Event is processed the Transitions of the current State will be searched for a Transition which can handle the event. If none is found the State's parent will be searched and so on.

构造器详细资料

State

public State(java.lang.String id)

Creates a new State with the specified id.

参数:

id - the unique id of this State.

State

public State(java.lang.String id,
     State parent)

Creates a new State with the specified id and parent.

参数:

id - the unique id of this State.

parent - the parent State.

方法详细资料

getId

public java.lang.String getId()

返回:

the id of this State.

getParent

public State getParent()

返回:

the parent or null if this State has no parent.

getTransitions

public java.util.List<Transition> getTransitions()

返回:

an unmodifiable List of Transitions going out from this State.

getOnEntrySelfTransitions

public java.util.List<SelfTransition> getOnEntrySelfTransitions()

返回:

an unmodifiable List of entry SelfTransitions

getOnExitSelfTransitions

public java.util.List<SelfTransition> getOnExitSelfTransitions()

返回:

an unmodifiable List of exit SelfTransitions

addTransition

public State addTransition(Transition transition)

Adds an outgoing Transition to this State with weight 0.

参数:

transition - the Transition to add.

返回:

this State.

另请参阅:

addTransition(Transition, int)

addTransition

public State addTransition(Transition transition,
                  int weight)

Adds an outgoing Transition to this State with the specified weight. The higher the weight the less important a Transition is. If two Transitions match the same Event the Transition with the lower weight will be executed.

参数:

transition - the Transition to add.

weight - The weight of this transition

返回:

this State.
