package org.drools.runtime;

A channel provides a mechanism to send objects from the working memory to some external process or function. For instance, a channel can be used to inform some piece of code that an object matches a rule.

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
   ...
 then
   channels["my-channel"].send(...);
 
public interface Channel {

    
Sends the given object to this channel.

Parameters:

    void send(Object object);
