* A channel provides a mechanism to send objects from the working memory to some external process

*

*
* To create a channel, implement the interface and register it with the KnowledgeRuntime:
*
*
* ...
* ksession.registerChannel("my-channel", new MyChannelImpl());
*
*
*
* Channels are invoked from the consequence side of a rule:

*
* when

* channels["my-channel"].send(...);
