public class SubscriberImpl
extends SubscriberPOA

A Subscriber is the object responsible for the actual reception of the data resulting from its subscriptions. A Subscriber acts on the behalf of one or several DataReader objects that are related to it. When it receives data (from the other parts of the system), it builds the list of concerned DataReader objects, and then indicates to the application that data is available, through its listener or by enabling related conditions. The application can access the list of concerned DataReader objects through the operation get_datareaders and then access the data available though operations on the DataReader.
