Class Subscriber.Convert<V,U>

java.lang.Object

com.tangosol.net.topic.Subscriber.Convert<V,U>

Type Parameters:

V - the type of the topic value

U - the type of the value returned to the subscriber

All Implemented Interfaces:

ExternalizableLite, PortableObject, Subscriber.Option<V,U>, Serializable

Enclosing interface:

Subscriber<V>

public static class Subscriber.Convert<V,U>
extends Object
implements Subscriber.Option<V,U>, ExternalizableLite, PortableObject

The Convert option specifies a Function that will convert topic values that a subscriber is interested in receiving prior to sending them to the subscriber. Note that all members of a subscriber group share a single converter. If members join the group using different converter then the last one to join will set the converter function for the group.
