Dynamic Creation of Topics in Hierarchy

If a topic matching certain topics in a hierarchy is created on a running server instance and its name matches any subscription expression, then this topic becomes the member of the hierarchy.
Example: Subscription expression: ABC.*
Topics existing on system: ABC, ABC.1, ABC.2, ABC.1.1
A subscriber looks up topics with expression ABC.* and it is receives messages from all matched topics. If at runtime a new topic named ABC.3 is created, thenABC.3 becomes a part of the hierarchy. Published messages on ABC.3 are received by the Subscriber created on ABC.*.
Note: For this feature to function, events must be enabled at the server end.
