Detailed Description

This class implements the message communication using a TCP/IP socket.

The object can connect to a server socket, or can use an already connected socket.

Definition at line 170 of file kmessageio.h.


Constructor & Destructor Documentation

KMessageSocket::KMessageSocket ( TQString  host,
TQ_UINT16  port,
TQObject *  parent = 0,
const char *  name = 0 
)

Connects to a server socket on /e host with /e port.

host can be an numerical (e.g. "192.168.0.212") or symbolic (e.g. "wave.peter.org") IP address. You can immediately use the /e sendSystem() and /e sendBroadcast() methods. The messages are stored and sent to the receiver after the connection is established.

If the connection could not be established (e.g. unknown host or no server socket at this port), the signal /e connectionBroken is emitted.

Definition at line 51 of file kmessageio.cpp.

KMessageSocket::KMessageSocket ( TQHostAddress  host,
TQ_UINT16  port,
TQObject *  parent = 0,
const char *  name = 0 
)

Connects to a server socket on /e host with /e port.

You can immediately use the /e sendSystem() and /e sendBroadcast() methods. The messages are stored and sent to the receiver after the connection is established.

If the connection could not be established (e.g. unknown host or no server socket at this port), the signal /e connectionBroken is emitted.

Definition at line 60 of file kmessageio.cpp.

KMessageSocket::KMessageSocket ( TQSocket *  socket,
TQObject *  parent = 0,
const char *  name = 0 
)

Uses /e socket to do the communication.

The socket should already be connected, or at least be in /e connecting state.

Note: The /e socket object is then owned by the /e KMessageSocket object. So don't use it otherwise any more and don't delete it. It is deleted together with this KMessageSocket object. (Use 0 as parent for the TQSocket object t ensure it is not deleted.)

Definition at line 69 of file kmessageio.cpp.

KMessageSocket::KMessageSocket ( int  socketFD,
TQObject *  parent = 0,
const char *  name = 0 
)

Uses the socket specified by the socket descriptor socketFD to do the communication.

The socket must already be connected.

This constructor can be used with a TQServerSocket within the (pure virtual) method /e newConnection.

Note: The socket is then owned by the /e KMessageSocket object. So don't manipulate the socket afterwards, especially don't close it. The socket is automatically closed when KMessageSocket is deleted.

Definition at line 77 of file kmessageio.cpp.

KMessageSocket::~KMessageSocket ( )

Destructor, closes the socket.

Definition at line 86 of file kmessageio.cpp.


Member Function Documentation

bool KMessageSocket::isConnected ( ) const [virtual]

Returns true if the socket is in state /e connected.

Reimplemented from KMessageIO.

Definition at line 91 of file kmessageio.cpp.

bool KMessageSocket::isNetwork ( ) const [inline, virtual]
Returns:
TRUE as this is a network IO.

Reimplemented from KMessageIO.

Definition at line 251 of file kmessageio.h.

TQString KMessageSocket::peerName ( ) const [virtual]
Since:
3.2
Returns:
The hostname this object is connected to. See TQSocket::peerName.

Reimplemented from KMessageIO.

Definition at line 173 of file kmessageio.cpp.

TQ_UINT16 KMessageSocket::peerPort ( ) const [virtual]
Since:
3.2
Returns:
The port that this object is connected to. See TQSocket::peerPort

Reimplemented from KMessageIO.

Definition at line 168 of file kmessageio.cpp.

virtual int KMessageSocket::rtti ( ) const [inline, virtual]

The runtime idendifcation.

Reimplemented from KMessageIO.

Definition at line 234 of file kmessageio.h.

void KMessageSocket::send ( const TQByteArray &  msg) [virtual]

Overwritten slot method from KMessageIO.

Note: It is not declared as a slot method, since the slot is already defined in KMessageIO as a virtual method.

Implements KMessageIO.
