There are several types of channels like TerminationChannel, ParentScopeChannel or CompensationChannel (their respective purpose should be obvious from their name). Some basic channels are provided to all activities when they're created to allow them to interact with their environment. When an activity wants to notifies its parent that it has terminated for example, it just calls its parent TerminationChannel (see the Empty example above).</p> <p>Don't look for channels implementations because there are none.

From Wikipedia: "A closure combines the code of a function with a special lexical environment bound to that function (scope). Closure lexical variables differ from global variables in that they do not occupy the global variable namespace. They differ from object oriented object variables in that they are bound to functions, not objects.". Normally closures aren't supported in Java so <a href="http://svn.apache.org/repos/asf/ode/trunk/jacob/src/main/java/org/apache/ode/jacob/JacobObject.java";>JacobObject</a> tries to feel that gap. But it's not a true closure anyway, which makes thing easier. Closures in JaCOb are statically coded, whereas in most languages supporting closures these are dynamic. So basically in JaCOb, a closure is expected to implement some methods and provides other utility methods to manipulate channels and replicate itself.</p> <p><a href="http://svn.apache.org/repos/asf/ode/trunk/jacob/src/main/java/org/apache/ode/jacob/JacobRunnable.java";>JacobRunnable</a> is just a JacobObject that requires the implementation of only one method: run().
