All Implemented Interfaces:

Externalizable, MethodFeedback, Serializable

public class ProgressCountFeedback

extends Object

implements MethodFeedback, Externalizable

Feedback object to carry progress count values to client. This class can be used by server-side methods to push progress count values to a client while an operation is being performed.

This class implements Externalizable as a performance improvement over Serializable.
