Detailed Description

A type of AudioSource which can be repositioned.

The basic AudioSource just streams continuously with no idea of a current time or length, so the PositionableAudioSource is used for a finite stream that has a current read position.

Destructor.

Member Function Documentation

◆ setNextReadPosition()

virtual void PositionableAudioSource::setNextReadPosition ( int64 newPosition)
pure virtual

Tells the stream to move to a new position.

Calling this indicates that the next call to AudioSource::getNextAudioBlock() should return samples from this position.

Note that this may be called on a different thread to getNextAudioBlock(), so the subclass should make sure it's synchronised.

Implemented in AudioFormatReaderSource, AudioTransportSource, BufferingAudioSource, and MemoryAudioSource.

◆ getNextReadPosition()

virtual int64 PositionableAudioSource::getNextReadPosition ( ) const
pure virtual

Returns the position from which the next block will be returned.

See also
setNextReadPosition

Implemented in AudioFormatReaderSource, AudioTransportSource, BufferingAudioSource, and MemoryAudioSource.

◆ getTotalLength()

virtual int64 PositionableAudioSource::getTotalLength ( ) const
pure virtual

Returns the total length of the stream (in samples).

Implemented in AudioFormatReaderSource, AudioTransportSource, BufferingAudioSource, and MemoryAudioSource.

◆ isLooping()

virtual bool PositionableAudioSource::isLooping ( ) const
pure virtual

Returns true if this source is actually playing in a loop.

Implemented in AudioFormatReaderSource, AudioTransportSource, BufferingAudioSource, and MemoryAudioSource.

◆ setLooping()

virtual void PositionableAudioSource::setLooping ( bool shouldLoop)
virtual

Tells the source whether you'd like it to play in a loop.

Reimplemented in AudioFormatReaderSource, and MemoryAudioSource.
