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). + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="QDataPump"></a>QDataPump::QDataPump ( <a href="qdatasource.html">QDataSource</a> * data_source, <a href="qdatasink.html">QDataSink</a> * data_sink ) +</h3> +Constructs a QDataPump to move data from a given <em>data_source</em> +to a given <em>data_sink</em>. + +<!-- eof --> +<hr><p> +This file is part of the <a href="index.html">Qt toolkit</a>. +Copyright © 1995-2007 +<a href="http://www.trolltech.com/">Trolltech</a>.
