Member Function Documentation

virtual Socket* Socket::Create

(

)

[inline, virtual]

Socket class instantiation method.

Used when a "non-standard" constructor needs to be used for the socket class. Note: the socket class still needs the "default" constructor with one ISocketHandler& as input parameter.

Definition at line 147 of file Socket.h.

Referenced by SctpSocket::PeelOff().

{ return NULL; }

ISocketHandler & Socket::Handler

(

)

const

Returns reference to sockethandler that owns the socket.

If the socket is detached, this is a reference to the slave sockethandler.

Definition at line 292 of file Socket.cpp.

ISocketHandler & Socket::MasterHandler

(

)

const

Returns reference to sockethandler that owns the socket.

This one always returns the reference to the original sockethandler, even if the socket is detached.

References m_handler.

        return m_handler;
}

void Socket::Init

(

)

[virtual]

Called by ListenSocket after accept but before socket is added to handler.

CTcpSocket uses this to create its ICrypt member variable. The ICrypt member variable is created by a virtual method, therefore it can't be called directly from the CTcpSocket constructor. Also used to determine if incoming HTTP connection is normal (port 80) or ssl (port 443).

Reimplemented in HttpDebugSocket.

SOCKET Socket::CreateSocket	(	int	af,
