QDataPump ( QDataSource *, QDataSink * )
DESCRIPTION
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).
MEMBER FUNCTION DOCUMENTATIONQDataPump::QDataPump ( QDataSource * data_source, QDataSink *
data_sink )
Constructs a QDataPump to move data from a given
data_source to a given data_sink.
