Package org.springframework.webflow.definition.registry Description

The flow definition registry subsystem for managing containers of flow definitions.

You can construct a generic, initially empty FlowDefinitionRegistry, populate it with flow definitions using a FlowDefinitionRegistrar, then lookup flow definitions by id. For example:

    // create registry
    FlowDefinitionRegistry registry = new FlowDefinitionRegistryImpl();

    // populate registry
    FlowDefinitionRegistrar registrar = ..
    registrar.addLocation(...);
    registrar.addLocation(...);
    registrar.registerFlowDefinitions(registry);

    // use registry
    FlowDefinition flow = registry.getFlow("myFlow");
