Examples of org.codehaus.activemq.message.ActiveMQTopic

org.codehaus.activemq.message.ActiveMQTopic
A Topic object encapsulates a provider-specific topic name. It is the way a client specifies the identity of a topic to JMS 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:
- Session.CreateConsumer(Destination destination)
- Session.CreateProducer(Destination destination)
Many publish/subscribe (pub/sub) providers group topics into hierarchies and provide various options for subscribing to parts of the hierarchy. The JMS 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 JMS 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 Topic objects. @see javax.jms.Session#createConsumer(javax.jms.Destination) @see javax.jms.Session#createProducer(javax.jms.Destination) @see javax.jms.TopicSession#createTopic(String)
