Detailed Description

+ + +This class is obsolete. It is provided to keep old source working. We strongly advise against using it in new code. +

The QDataPump class moves data from a QDataSource to a QDataSink during event processing. +

For a QDataSource to provide data to a QDataSink, a controller must exist +to examine the QDataSource::readyToSend() and QDataSink::readyToReceive() +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. +

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). + +
