net.shibboleth.idp.profile.spring.factory.FlowModelFlowBuilder

All Implemented Interfaces:

FlowBuilder

public class FlowModelFlowBuilder
extends AbstractFlowBuilder

This code is extended from FlowModelFlowBuilder in order to customize the Spring ApplicationContext used for flow configuration. The only method changed is createFlowApplicationContext(String[]) (parameter changed from Resource, but it's private and there are too many threads pulled by anything but a wholesale duplication of this class). Builds a runtime Flow definition object from a FlowModel.

FlowBuilderException - an exception occurred building the flow

createFlow

protected Flow createFlow()

Overrides:

createFlow in class AbstractFlowBuilder
