Wildcards in Topics
TIBCO Enterprise Message Service enables you to use wildcards in topic names in some situations.
- You can subscribe to wildcard topics.
If you subscribe to a topic containing a wildcard, you will receive any message published to a matching topic. For example, if you subscribe to
foo.*
you will receive messages published to a topic namedfoo.bar
.You can subscribe to a wildcard topic (for example
foo.*
), whether or not there is a matching topic in the configuration file (for example,foo.*
,foo.>
, orfoo.bar
). However, if there is no matching topic name in the configuration file, no messages will be published on that topic. - You cannot publish to wildcard topics.
- If
foo.bar
is not in the configuration file, then you can publish tofoo.bar
iffoo.*
orfoo.>
exists in the configuration file. - On routed topic messages, subscribers must specify a topic that is a direct subset (or equal) of the configured global topic. For more information, see Wildcards.
