Topics

Topics must start with a '/' character and can be wildcards.

Wildcard Topics

• ** can be used at the end of a topic to match all subtopics
• * can be used at the end of a topic to match all subtopics in the next level

eg:

• /chat/** will match /chat/cars and /chat/cars/bmw
• /chat/* will match /chat/cars but WILL NOT MATCH /chat/cars/bmw
• /** will match all topics

Techie Stuff

Under the hood, a topic is a grouping of CometD channels. This abstraction allows multiple PushTargets to subscribe to the same topic but apply different actions and formatting to the messages.
