org.springframework.webflow.engine.builder.FlowAssembler.assembleFlow()
Assembles the flow, directing the construction process by delegating to the configured FlowBuilder. Every call to this method will assemble the Flow instance.
This will drive the flow construction process as described in the {@link FlowBuilder} JavaDoc, starting withbuilder initialization using {@link FlowBuilder#init(FlowBuilderContext)} and finishing by cleaning up thebuilder with a call to {@link FlowBuilder#dispose()}. @return the constructed flow @throws FlowBuilderException when flow assembly fails
