java.lang.Object

org.apache.hadoop.yarn.state.StateMachineFactory<OPERAND,STATE,EVENTTYPE,EVENT>

型パラメータ:

OPERAND - The object type on which this state machine operates.

STATE - The state of the entity.

EVENTTYPE - The external eventType to be handled.

EVENT - The event object.

@InterfaceAudience.Public
 @InterfaceStability.Evolving
public final class StateMachineFactory<OPERAND,STATE extends Enum<STATE>,EVENTTYPE extends Enum<EVENTTYPE>,EVENT>
extends Object

State machine topology. This object is semantically immutable. If you have a StateMachineFactory there's no operation in the API that changes its semantic properties.

hook - transition hook

戻り値:

a NEW StateMachineFactory just like this with the current transition added as a new legal transition Note that the returned StateMachineFactory is a distinct object. This method is part of the API.

installTopology

public StateMachineFactory<OPERAND,STATE,EVENTTYPE,EVENT> installTopology()

戻り値:

a StateMachineFactory just like this, except that if you won't need any synchronization to build a state machine Note that the returned StateMachineFactory is a distinct object. This method is part of the API. The only way you could distinguish the returned StateMachineFactory from this would be by measuring the performance of the derived StateMachine you can get from it. Calling this is optional. It doesn't change the semantics of the factory, if you call it then when you use the factory there is no synchronization.

make

public StateMachine<STATE,EVENTTYPE,EVENT> make(OPERAND operand,
                                                STATE initialState)

make

public StateMachine<STATE,EVENTTYPE,EVENT> make(OPERAND operand)

generateStateGraph

public org.apache.hadoop.yarn.state.Graph generateStateGraph(String name)

Generate a graph represents the state graph of this StateMachine

パラメータ:

name - graph name

戻り値:

Graph object generated
