Syntax
class IMessageTransportHandler
Remarks
Interface for message transport event handlers.
This interface is typically implemented by message bridges and other classes that manage a message transport and wish to receive messages from it. This interface also notifies implementors of discovered and lost transport nodes.
A transport node is the internal representation of a remote message endpoint that may exist in a different process or on a different computer. The actual implementation of these nodes depends on the transport layer. It may be a network socket connection, a named pipe, or some other communication technology.
Each transport node gets a globally unique identifier that can be used by a message bridge to translate local message addresses to remote message endpoints. When a message endpoint on the message bus sends a message to a specific message address that represents a remote endpoint, the message bridge maps the address to a transport identifier, which is then mapped again to the corresponding connection in the transport layer.
