Detailed Description

To avoid creating a CorbaPublisher for each message to publish, an pool of CorbaPublisher has been introduced by means of a HashMap. The key of the HasMap is the name of the NC. To made the publisher reusable for all the topics, the HashMap is static.

The DefaultPublisherImpl instantiates an object of this class and publishes messages passing the topic i.e. it never calls the method without topic. In particular it calls:

publish(Topic,Message) for Heartbeat, Category, clients
publish(Topic topic, Message message, int deliveryMode, int priority, long timeToLive) for Sources

For our point of view the two methods have the same functioning because we do not use the deliveryMode, priority and timeToLive at least for now ;-)

Publish a message in the topic

The topic is the topic whose name has been passed in the constructor. However for this implementation there is no difference when the topic has been built because all the topics are in the pool. The name of the topic built in the constructor can be accessed through the topicName field.
