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.

Member Function Documentation

getNextReadPosition()

virtual int64 juce::PositionableAudioSource::getNextReadPosition ( ) const

pure virtual

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

See also

setNextReadPosition

Implemented in juce::AudioTransportSource, juce::BufferingAudioSource, and juce::AudioFormatReaderSource.

getTotalLength()

virtual int64 juce::PositionableAudioSource::getTotalLength ( ) const

pure virtual

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

Implemented in juce::AudioTransportSource, juce::BufferingAudioSource, and juce::AudioFormatReaderSource.

isLooping()

virtual bool juce::PositionableAudioSource::isLooping ( ) const

pure virtual

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

Implemented in juce::AudioTransportSource, juce::BufferingAudioSource, and juce::AudioFormatReaderSource.

setLooping()

virtual void juce::PositionableAudioSource::setLooping ( bool  shouldLoop )

inlinevirtual

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

Reimplemented in juce::AudioFormatReaderSource.

setNextReadPosition()

virtual void juce::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 juce::AudioTransportSource, juce::BufferingAudioSource, and juce::AudioFormatReaderSource.
