class aiocoap.transports.generic_udp.GenericMessageInterface(mman: aiocoap.interfaces.MessageManager, log, loop)

Bases: aiocoap.interfaces.MessageInterface

GenericMessageInterface is not a standalone implementation of a message inteface. It does implement everything between the MessageInterface and a not yet fully specified interface of “bound UDP sockets”.

It delegates sending through the address objects (which persist through some time, given this is some kind of bound-socket scenario).

The user must: * set up a ._pool after construction with a shutdown and a connect method * provide their addresses with a send(bytes) method * pass incoming data to the _received_datagram and _received_exception methods


Send a given Message object


Return a value suitable for the message’s remote property based on its .opt.uri_host or .unresolved_remote.

May return None, which indicates that the MessageInterface can not transport the message (typically because it is of the wrong scheme).


Deactivate the complete transport, usually irrevertably. When the coroutine returns, the object must have made sure that it can be destructed by means of ref-counting or a garbage collector run.
