StateMachineFactory(STATE defaultInitialState)
Constructor
This is the only constructor in the API.

public StateMachineFactory(STATE defaultInitialState)
public StateMachineFactory<OPERAND,STATE,EVENTTYPE,EVENT> addTransition(STATE preState, STATE postState, EVENTTYPE eventType)
preState
- pre-transition statepostState
- post-transition stateeventType
- stimulus for the transitionthis
with the current
transition added as a new legal transition. This overload
has no hook object.
Note that the returned StateMachineFactory is a distinct
object.
This method is part of the API.public StateMachineFactory<OPERAND,STATE,EVENTTYPE,EVENT> addTransition(STATE preState, STATE postState, Set<EVENTTYPE> eventTypes)
preState
- pre-transition statepostState
- post-transition stateeventTypes
- List of stimuli for the transitionsthis
with the current
transition added as a new legal transition. This overload
has no hook object.
Note that the returned StateMachineFactory is a distinct
object.
This method is part of the API.public StateMachineFactory<OPERAND,STATE,EVENTTYPE,EVENT> addTransition(STATE preState, STATE postState, Set<EVENTTYPE> eventTypes, SingleArcTransition<OPERAND,EVENT> hook)
preState
- pre-transition statepostState
- post-transition stateeventTypes
- List of stimuli for the transitionshook
- transition hookthis
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.public StateMachineFactory<OPERAND,STATE,EVENTTYPE,EVENT> addTransition(STATE preState, STATE postState, EVENTTYPE eventType, SingleArcTransition<OPERAND,EVENT> hook)
preState
- pre-transition statepostState
- post-transition stateeventType
- stimulus for the transitionhook
- transition hookthis
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.public StateMachineFactory<OPERAND,STATE,EVENTTYPE,EVENT> addTransition(STATE preState, Set<STATE> postStates, EVENTTYPE eventType, MultipleArcTransition<OPERAND,EVENT,STATE> hook)
preState
- pre-transition statepostStates
- valid post-transition stateseventType
- stimulus for the transitionhook
- transition hookthis
with the current
transition added as a new legal transition
Note that the returned StateMachineFactory is a distinct object.

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