7.9.3.3 Server Implementation
The base of the server are the two classes
CKVCServer
and
CKVCConnec-
tion
. The class
CKVCServer
establishes and manages the connections. The
class
CKVCConnection
constitutes the actual connection.
To correctly implement a server, a derivation of the class
CKVCServer
is nee-
ded.
class CKVCTestServer: public CKVCServer{
public:
CKVCTestServer();
virtual ~CKVCTestServer();
CKVCConnection* OnClientConnect(SOCKET socket,
sockaddr_in &sockAdr);
int OnClientDisconnect(CKVCConnection *pConnection,
TKVCDisconInfo info);
};
In this class, the method
OnClientConnect
must be overwritten. In this
method, a
CKVCConnection
object must be created and initialized.
CKVCConnection* CKVCTestServer::OnClientConnect(SOCKET socket,
sockaddr_in &sockAdr){
CKVCTestConnection *pConnect = 0;
... pConnect = new CKVCTestConnection();
if (pConnect != 0){
pConnect->Init(this, socket, sockAdr);
}
...
return pConnect;
}
The method
OnClientDisconnect
can be overwritten. But it must be guar-
anteed that the method
CKVCServer::OnClientDisconnect
is called in
this derivation.
int CKVCTestServer::OnClientDisconnect(CKVCConnection
*pConnection,
TKVCDisconInfo info){
...
