then transfer data between them until the connection is
closed. This is often useful for testing a protocol.
Parameters | server | The protocol instance representing the server-side of this connection. |
client | The protocol instance representing the client-side of this connection. | |
pumpPolicy | When either server or client writes to its
transport, the string passed in is added to a queue of data for the other
protocol. Eventually, pumpPolicy will be called with one such
queue and the corresponding protocol object. The pump policy callable is
responsible for emptying the queue and passing the strings it contains to
the given protocol's dataReceived method. The signature of
pumpPolicy is (queue, protocol) .
queue is an object with a get method which will
return the next string written to the transport, or None if
the transport has been disconnected, and which evaluates to
True if and only if there are more items to be retrieved via
get .

Returns | A Deferred which
fires when the connection has been closed and both sides have received
notification of this.
|
Parameters | server | The protocol instance representing the server-side of this connection. |
serverToClient | The _LoopbackQueue
holding the server's output.
| |
client | The protocol instance representing the client-side of this connection. | |
clientToServer | The _LoopbackQueue
holding the client's output.

pumpPolicy | See loopbackAsync .
