#include <qasyncio.h>
Inherits QAsyncIO.
Public Members
virtual int readyToReceive ()
virtual void receive ( const uchar *, int count )
virtual void eof ()
void maybeReady ()
DESCRIPTION
The QDataSink class is an asynchronous consumer of data.
A data sink is an object which receives data from some
source in an asynchronous manner. This means that at some
time not determined by the data sink, blocks of data are
given to it from processing. The data sink is able to
limit the maximum size of such blocks which it is
currently able to process.
See also QAsyncIO, QDataSource and QDataPump.
MEMBER FUNCTION DOCUMENTATIONvoid QDataSink::eof () [virtual]
This function will be called when no more data is
available for processing.
void QDataSink::maybeReady ()
This should be called whenever readyToReceive() might have
become non-zero. It is merely calls QAsyncIO::ready() if
readyToReceive() is non-zero.
int QDataSink::readyToReceive () [virtual]
The data sink should return a value indicating how much
data it is ready to consume. This may be 0.
void QDataSink::receive ( const uchar *, int count ) [virtual]
This function is called to provide data for the data sink.
The count will be no more than the amount indicated by the
most recent call to readyToReceive(). The sink must use
all the provided data.
