| Interface | Description | 
|---|---|
| Assertor | API used in the to allow a message exchange participant to
 assert its capabilities for the underlying message. | 
| Conduit | A pipe between peers that channels transport-level messages. | 
| ConduitInitiator | Factory for Conduits. | 
| ConduitInitiatorManager | The ConduitInitiatorManager provides an interface to register and retrieve
 transport factories. | 
| Destination | A Destination is a transport-level endpoint capable of receiving
 unsolicited incoming messages from different peers. | 
| DestinationFactory | Factory for Destinations. | 
| DestinationFactoryManager | The DestinationFactoryManager provides an interface to register and retrieve
 transport factories. | 
| DestinationWithEndpoint | A destination that has a specific endpoint. | 
| MessageObserver | Observer for incoming messages. | 
| MultiplexDestination | A MultiplexDestination is a transport-level endpoint capable of receiving
 unsolicited incoming messages from different peers for multiple targets
 identified by a unique id. | 
| Observable | Allows Observers to register for notification on incoming messages. | 
| Session | A Session which can be bound to HTTP, WS-Adddressing, etc. | 
| Class | Description | 
|---|---|
| AbstractConduit | Abstract base class factoring out common Conduit logic,
 allowing non-decoupled transports to be written without any
 regard for the decoupled back-channel or partial response logic. | 
| AbstractDestination | Abstract base class factoring out common Destination logic,
 allowing non-decoupled transports to be written without any
 regard for the decoupled back-channel or partial response logic. | 
| AbstractMultiplexDestination | |
| AbstractObservable | |
| AbstractTransportFactory | Helper methods for  DestinationFactorys andConduitInitiators. | 
| ChainInitiationObserver | |
| HttpUriMapper | |
| MultipleEndpointObserver | This MessageObserver creates an Interceptor chain which adds in the interceptors
 set on this class and the global Bus interceptors. | 
| TransportFinder<T> | |
| TransportURIResolver |
