Detailed Description
This class is obsolete. It is provided to keep old source working. We strongly advise against using it in new code.
The TQIODeviceSource class is a TQDataSource that draws data from a TQIODevice.
This class encapsulates retrieving data from a TQIODevice (such as a TQFile).
Member Function Documentation
TQIODeviceSource::TQIODeviceSource ( TQIODevice * device, int buffer_size = 4096 )
Constructs a TQIODeviceSource from the TQIODevice device. The TQIODevice
must be dynamically allocated, becomes owned by the TQIODeviceSource,
and will be deleted when the TQIODeviceSource is destroyed. buffer_size
determines the size of buffering to use between asynchronous operations.
The higher the buffer_size, the more efficient, but the less interleaved
the operation will be with other processing.
TQIODeviceSource::~TQIODeviceSource ()
Destroys the TQIODeviceSource, deleting the TQIODevice from which it was
constructed.
void TQIODeviceSource::enableRewind ( bool on ) [virtual]
If on is set to TRUE then rewinding is enabled.
No special action is taken. If on is set to
FALSE then rewinding is disabled.
Reimplemented from TQDataSource.
int TQIODeviceSource::readyToSend () [virtual]
Ready until end-of-file.
Reimplemented from TQDataSource.
void TQIODeviceSource::rewind () [virtual]
Calls reset() on the TQIODevice.
Reimplemented from TQDataSource.
bool TQIODeviceSource::rewindable () const [virtual]
All TQIODeviceSource's are rewindable.
Reimplemented from TQDataSource.
void TQIODeviceSource::sendTo ( TQDataSink * sink, int n ) [virtual]
Reads a block of data and sends up to n bytes to the sink.
Reimplemented from TQDataSource.
