Class ConsumerRegistryImpl

java.lang.Object
  org.apache.wsrp4j.producer.driver.ConsumerRegistryImpl

All Implemented Interfaces:

ConsumerRegistry

public class ConsumerRegistryImpl

extends java.lang.Object

implements ConsumerRegistry

This class implements the ConsumerRegistry interface. All registrations are kept within a hashmap associating registration handles (keys) with registration-objects (values). Provides different access methods.

TODO:

• Synchronization aspects are not considered so far. This could be achieved by using a hashtable instead of a hashmap.
