Member Function Documentation

abort()

void QNetworkReplyDataImpl::abort ( )

overridevirtual

Aborts the operation immediately and close down any network connections still open.

Uploads still in progress are also aborted.

The finished() signal will also be emitted.

See also

close(), finished()

Implements QNetworkReply.

Definition at line 66 of file qnetworkreplydataimpl.cpp.

References QNetworkReply::close().

Here is the call graph for this function:

bytesAvailable()

qint64 QNetworkReplyDataImpl::bytesAvailable ( ) const

overridevirtual

Returns the number of bytes that are available for reading.

This function is commonly used with sequential devices to determine the number of bytes to allocate in a buffer before reading.

Subclasses that reimplement this function must call the base implementation in order to include the size of the buffer of QIODevice. Example:

qint64 CustomDevice::bytesAvailable() const
{
    return buffer.size() + QIODevice::bytesAvailable();
}

See also

bytesToWrite(), readyRead(), isSequential()

Reimplemented from QIODevice.

Definition at line 71 of file qnetworkreplydataimpl.cpp.

References QIODevice::bytesAvailable(), and d.

Here is the call graph for this function:

close()

void QNetworkReplyDataImpl::close ( )

overridevirtual

Closes this device for reading.

Unread data is discarded, but the network resources are not discarded until they are finished. In particular, if any upload is in progress, it will continue until it is done.

The finished() signal is emitted when all operations are over and the network resources are freed.

See also

abort(), finished()

Reimplemented from QNetworkReply.

Definition at line 61 of file qnetworkreplydataimpl.cpp.

References QNetworkReply::close().

Here is the call graph for this function:

isSequential()

bool QNetworkReplyDataImpl::isSequential ( ) const

overridevirtual

Reimplemented from QNetworkReply.

Definition at line 77 of file qnetworkreplydataimpl.cpp.

readData()

qint64 QNetworkReplyDataImpl::readData ( char *  data, qint64  maxlen  )

overridevirtual

Implements QIODevice.

Definition at line 91 of file qnetworkreplydataimpl.cpp.

References d.

size()

qint64 QNetworkReplyDataImpl::size ( ) const

overridevirtual

For open random-access devices, this function returns the size of the device.

For open sequential devices, bytesAvailable() is returned.

If the device is closed, the size returned will not reflect the actual size of the device.

isSequential(), pos()
