|
|
|
|
|
|
<b>This class is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
|
|
<p> The QDataPump class moves data from a QDataSource to a QDataSink during event processing.
|
|
<p> For a QDataSource to provide data to a QDataSink, a controller must exist
|
|
to examine the <a href="qdatasource.html#readyToSend">QDataSource::readyToSend</a>() and <a href="qdatasink.html#readyToReceive">QDataSink::readyToReceive</a>()
|
|
methods and respond to the QASyncIO::activate() signal of the source and
|
|
sink. One very useful way to do this is interleaved with other event
|
|
processing. QDataPump provides this - create a pipe between a source
|
|
and a sink, and data will be moved during subsequent event processing.
|
|
<p> Note that each source can only provide data to one sink and each sink
|
|
can only receive data from one source (although it is quite possible
|
|
to write a multiplexing sink that is multiple sources).
|
