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 ValueExtractor 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.
