|
|
|
|
|
|
<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This class is obsolete.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 TQDataPump class moves data from a TQDataSource to a TQDataSink during event processing.
|
|
<p> For a TQDataSource to provide data to a TQDataSink, a controller must exist
|
|
to examine the <a href="qdatasource.html#readyToSend">TQDataSource::readyToSend</a>() and <a href="qdatasink.html#readyToReceive">TQDataSink::readyToReceive</a>()
|
|
methods and respond to the TQASyncIO::activate() signal of the source and
|
|
sink. One very useful way to do this is interleaved with other event
|
|
processing. TQDataPump 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).
|
