public abstract class ViewSelection
extends java.lang.Object
implements java.io.Serializable

Abstract base class for value objects that provide callers into a flow execution information about a logical response to issue and the data necessary to issue it.

This class is a generic marker returned when a request into an executing flow has completed processing, indicating a client response needs to be issued. An instance of a ViewSelection subclass represents the selection of a concrete response type. It is expected that callers introspect the returned view selection instance to handle the response types they support.
