public interface Topic extends Destination
Topicobject encapsulates a provider-specific topic name.
It is the way a client specifies the identity of a topic to Jakarta Messaging API methods. For those methods that use a
Destination as a parameter, a
Topic object may used as an argument . For example, a Topic can be used
to create a
MessageConsumer and a
MessageProducer by calling:
Many publish/subscribe (pub/sub) providers group topics into hierarchies and provide various options for subscribing
to parts of the hierarchy. The Jakarta Messaging API places no restriction on what a
Topic object represents. It may be a
leaf in a topic hierarchy, or it may be a larger part of the hierarchy.
The organization of topics and the granularity of subscriptions to them is an important part of a pub/sub
application's architecture. The Jakarta Messaging API does not specify a policy for how this should be done. If an application
takes advantage of a provider-specific topic-grouping mechanism, it should document this. If the application is
installed using a different provider, it is the job of the administrator to construct an equivalent topic
architecture and create equivalent
