Detailed Description

+ + +This class is obsolete.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

The QIODeviceSource class is a QDataSource that draws data from a QIODevice. +

This class encapsulates retrieving data from a QIODevice (such as a QFile). + +

Member Function Documentation

+

QIODeviceSource::QIODeviceSource ( QIODevice * device, int buffer_size = 4096 ) +

+Constructs a QIODeviceSource from the QIODevice device. The QIODevice +must be dynamically allocated, becomes owned by the QIODeviceSource, +and will be deleted when the QIODeviceSource 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. + +

QIODeviceSource::~QIODeviceSource () +

+Destroys the QIODeviceSource, deleting the QIODevice from which it was +constructed. + +

void QIODeviceSource::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 QDataSource. +

int QIODeviceSource::readyToSend () [virtual] +

+Ready until end-of-file. + +

Reimplemented from QDataSource. +

void QIODeviceSource::rewind () [virtual] +

+Calls reset() on the QIODevice. + +

Reimplemented from QDataSource. +

bool QIODeviceSource::rewindable () const [virtual] +

+All QIODeviceSource's are rewindable. + +

Reimplemented from QDataSource. +

void QIODeviceSource::sendTo ( QDataSink * sink, int n ) [virtual] +

+Reads a block of data and sends up to n bytes to the sink. + +
