public interface WorkContext

WorkContext is a marker interface used for marshaling and unmarshaling user data in a WorkArea. The interfaces WorkContextOutput and WorkContextInput will only allow primtive types and objects implementing WorkContext to be marshaled. This limits the type surface area that needs to be dealt with by underlying protocols. WorkContext is analogous to Externalizable but with some restrictions on the types that can be marshaled. Advanced Externalizable features, such as enveloping, are not supported - implementations should provide their own versioning scheme if necessary. WorkContext implementations must provide a public no-arg constructor.
