Examples of org.springframework.webflow.engine.EndState

org.springframework.webflow.engine.EndState
A state that ends a flow when entered. This state ends the active flow session of an ongoing flow execution.
If the ended session is the "root flow session" the entire flow execution ends, signaling the end of a logical conversation.
If the terminated session was acting as a subflow, the flow execution continues and control is returned to the parent flow session. In that case, this state returns an ending result event the resuming parent flow responds to.
An end state may be configured with a renderer to render a final response. This renderer will be invoked if the end state terminates the entire flow execution. @see org.springframework.webflow.engine.SubflowState @author Keith Donald @author Colin Sampaleanu @author Erwin Vervaet
