// Class : CConnectionRepository
|
|
// Description : This class implements the C++ side of the
|
|
// ConnectionRepository object. In particular, it
|
|
// manages the connection to the server once it has been
|
|
// opened (but does not open it directly). It manages
|
|
// reading and writing datagrams on the connection and
|
|
// monitoring for unexpected disconnects as well as
|
|
// handling intentional disconnects.
|
|
//
|
|
// Certain server messages, like field updates, are
|
|
// handled entirely within the C++ layer, while server
|
|
// messages that are not understood by the C++ layer are
|
|
// returned up to the Python layer for processing.
