Detailed Description

Buffered stream sockets.

This class allows the user to create and operate buffered stream sockets such as those used in most Internet connections. This class is also the one that resembles the most to the old QSocket implementation.

Objects of this type operate only in non-blocking mode. A call to setBlocking(true) will result in an error.

Note:
Buffered sockets only make sense if you're using them from the main (event-loop) thread. This is actually a restriction imposed by Qt's TQSocketNotifier. If you want to use a socket in an auxiliary thread, please use KStreamSocket.

Member Function Documentation

void KNetwork::TDEBufferedSocket::bytesWritten ( int  bytes  )  [signal]

This signal is emitted whenever data is written.

bool KNetwork::TDEBufferedSocket::canReadLine (  )  const

Returns true if a line can be read with readLine.

void TDEBufferedSocket::close (  )  [virtual]

Closes the socket for new data, but allow data that had been buffered for output with writeBlock to be still be written.

See also:
closeNow

Reimplemented from KNetwork::KClientSocketBase.

Definition at line 82 of file kbufferedsocket.cpp.

virtual void KNetwork::TDEBufferedSocket::closeNow (  )  [virtual]

Returns the length of the output buffer.

Closes the socket and discards any output data that had been buffered with writeBlock but that had not yet been written.

See also:
close
void TDEBufferedSocket::enableRead ( bool  enable  )  [virtual]

Catch changes.

Reimplemented from KNetwork::KClientSocketBase.

Definition at line 202 of file kbufferedsocket.cpp.

void TDEBufferedSocket::enableWrite ( bool  enable  )  [virtual]

Catch changes.

Reimplemented from KNetwork::KClientSocketBase.

Definition at line 219 of file kbufferedsocket.cpp.

TDEIOBufferBase * TDEBufferedSocket::inputBuffer (  ) 

Retrieves the input buffer object.

Definition at line 263 of file kbufferedsocket.cpp.

TDEIOBufferBase * TDEBufferedSocket::outputBuffer (  ) 

Retrieves the output buffer object.

Definition at line 282 of file kbufferedsocket.cpp.

TQ_LONG TDEBufferedSocket::peekBlock ( char *  data,
TQ_ULONG  maxlen,
TDESocketAddress &  from

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Peeks data from the socket.

The from parameter is always set to peerAddress()

Reimplemented from KNetwork::KClientSocketBase.

Definition at line 159 of file kbufferedsocket.cpp.

TQ_LONG TDEBufferedSocket::peekBlock ( char *  data,
TQ_ULONG  maxlen 
) [virtual]

Peeks data from the socket.

Reimplemented from KNetwork::KClientSocketBase.

Definition at line 143 of file kbufferedsocket.cpp.

TQCString KNetwork::TDEBufferedSocket::readLine (  ) 

Reads a line of data from the socket buffers.

void TDEBufferedSocket::setInputBuffering ( bool  enable  ) 

Sets the use of input buffering.

Definition at line 249 of file kbufferedsocket.cpp.

void TDEBufferedSocket::setOutputBuffering ( bool  enable  ) 

Sets the use of output buffering.

Definition at line 268 of file kbufferedsocket.cpp.

void TDEBufferedSocket::setSocketDevice ( TDESocketDevice *  device  )  [virtual]

Be sure to catch new devices.

Reimplemented from KNetwork::TDESocketBase.

Definition at line 67 of file kbufferedsocket.cpp.

bool TDEBufferedSocket::setSocketOptions ( int  opts  )  [protected, virtual]

Buffered sockets can only operate in non-blocking mode.

Reimplemented from KNetwork::KClientSocketBase.

Definition at line 73 of file kbufferedsocket.cpp.

virtual void KNetwork::TDEBufferedSocket::slotReadActivity (  )  [protected, virtual, slot]

Slot called when there's read activity.

Reimplemented from KNetwork::KClientSocketBase.

virtual void KNetwork::TDEBufferedSocket::slotWriteActivity (  )  [protected, virtual, slot]

Slot called when there's write activity.

Reimplemented from KNetwork::KClientSocketBase.

void TDEBufferedSocket::stateChanging ( SocketState  newState  )  [protected, virtual]

Catch connection to clear the buffers.

Reimplemented from KNetwork::KClientSocketBase.

Definition at line 231 of file kbufferedsocket.cpp.

TQT_TQIO_LONG TDEBufferedSocket::tqreadBlock ( char *  data,
TQT_TQIO_ULONG  maxlen,
TDESocketAddress &  from 
) [virtual]

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Reads data from a socket.

The from parameter is always set to peerAddress()

Reimplemented from KNetwork::KClientSocketBase.

Definition at line 137 of file kbufferedsocket.cpp.

TQT_TQIO_LONG TDEBufferedSocket::tqreadBlock ( char *  data,
TQT_TQIO_ULONG  maxlen 
) [virtual]

Reads data from the socket.

Make use of buffers.

TQT_TQIO_LONG TDEBufferedSocket::tqwriteBlock ( const char *  data,
TQT_TQIO_ULONG  len,
const TDESocketAddress &  to 
) [virtual]

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Writes data to the socket.

The to parameter is discarded.

Reimplemented from KNetwork::KClientSocketBase.

Definition at line 195 of file kbufferedsocket.cpp.

TQT_TQIO_LONG TDEBufferedSocket::tqwriteBlock ( const char *  data,
TQT_TQIO_ULONG  len 
) [virtual]

Writes data to the socket.

Reimplemented from KNetwork::KClientSocketBase.

Definition at line 165 of file kbufferedsocket.cpp.

void KNetwork::TDEBufferedSocket::waitForConnect (  ) 

Blocks until the connection is either established, or completely failed.

TQ_LONG TDEBufferedSocket::waitForMore ( int  msecs,
bool *  timeout = 0L 
) [virtual]
