Constructor Details

AbstractStateMachineFactory

public AbstractStateMachineFactory(StateMachineModel<S,E> defaultStateMachineModel,
 StateMachineModelFactory<S,E> stateMachineModelFactory)

Instantiates a new abstract state machine factory.

Parameters:

defaultStateMachineModel - the default state machine model

stateMachineModelFactory - the state machine model factory

Method Details

setBeanName

public void setBeanName(String name)

Specified by:

setBeanName in interface org.springframework.beans.factory.BeanNameAware

getStateMachine

public StateMachine<S,E> getStateMachine()

Description copied from interface: StateMachineFactory

Build a new StateMachine instance.

Specified by:

getStateMachine in interface StateMachineFactory<S,E>

Returns:

a new state machine instance.

getStateMachine

public StateMachine<S,E> getStateMachine(String machineId)

Description copied from interface: StateMachineFactory

Build a new StateMachine instance with a given machine id.

Specified by:
