Member Function Documentation

◆ atEnd()

bool QSoundEffectPrivateSynchronous::atEnd ( ) const
overridevirtual

Returns true if the current read and write position is at the end of the device (i.e.

there is no more data available for reading on the device); otherwise returns false.

For some devices, atEnd() can return true even though there is more data to read. This special case only applies to devices that generate data in direct response to you calling read() (e.g., /dev or /proc files on Unix and \macos, or console input / stdin on all platforms).

◆ bytesAvailable()

qint64 QSoundEffectPrivateSynchronous::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:

◆ decoderError()

Definition at line 211 of file qsoundeffectsynchronous.cpp.

◆ isSequential()

bool QSoundEffectPrivateSynchronous::isSequential ( ) const
overridevirtual

Returns true if this device is sequential; otherwise returns false.

Sequential devices, as opposed to a random-access devices, have no concept of a start, an end, a size, or a current position, and they do not support seeking. You can only read from the device when it reports that data is available. The most common example of a sequential device is a network socket. On Unix, special files such as /dev/zero and fifo pipes are sequential.

Regular files, on the other hand, do support random access. They have both a size and a current position, and they also support seeking backwards and forwards in the data stream. Regular files are non-sequential.

◆ readData()

qint64 QSoundEffectPrivateSynchronous::readData ( char * data,
qint64 maxSize )
overridevirtual

Reads up to maxSize bytes from the device into data, and returns the number of bytes read or -1 if an error occurred.

If there are no bytes to be read and there can never be more bytes available (examples include socket closed, pipe closed, sub-process finished), this function returns -1.

This function is called by QIODevice. Reimplement this function when creating a subclass of QIODevice.

When reimplementing this function it is important that this function reads all the required data before returning. This is required in order for QDataStream to be able to operate on the class. QDataStream assumes all the requested information was read and therefore does not retry reading if there was a problem.

This function might be called with a maxSize of 0, which can be used to perform post-reading operations.

When reimplementing this function it is important that this function writes all the data available before returning. This is required in order for QDataStream to be able to operate on the class.
