org.springframework.statemachine.config.model

Class AbstractStateMachineModelFactory<S,E>

java.lang.Object

org.springframework.statemachine.config.model.AbstractStateMachineModelFactory<S,E>

Type Parameters:

S - the type of state

E - the type of event

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.context.ResourceLoaderAware, StateMachineComponentResolver<S,E>

Direct Known Subclasses:

UmlStateMachineModelFactory

public abstract class AbstractStateMachineModelFactory<S,E>
extends java.lang.Object
implements StateMachineComponentResolver<S,E>, org.springframework.beans.factory.BeanFactoryAware, org.springframework.context.ResourceLoaderAware

Base implementation of a StateMachineModelFactory providing some common grounds for various implementations. This factory is able to resolve Actions or Guards either from a BeanFactory if knows, or from manually registered instances. Manually registered actions or guards are needed if those are not created as beans or if whole state machine is working outside of an application context.
