IChannel and IQueueChannel are incompatible #10

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
It is impossible to create generic code that use interfaces and then decide to 
use the event model (Channel) or queue model (QueueChannel) later.

Proposal: drop the IQueueChannel interface altogether and have QueueChannel 
implement IChannel.

Alternative Proposal: have IQueueChannel be the base interface and IChannel 
inherit from that.

IQueueChannel has two methods and no sub-interfaces:
* void Publish(T message)
* IDisposable Subscribe(IExecutionContext, Action<T>)

IChannel has the same two methods (note: IExecutionContext is an IFiber in this 
case, but IFiber is an IExecutionContext) along with a set of other 
subscription models.  There is no reason why there has to be the separation.

Not sure on this one.  

1) QueueChannel doesn't support many of the methods on IChannel.
2) Not sure how I feel about having IChannel implement IQueueChannel.  Perhaps 
if we came up with better names?
