## 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.

## Constructor & Destructor Documentation

## ◆ PositionableAudioSource()

juce::PositionableAudioSource::PositionableAudioSource | ( |  | ) |
| protected default

Creates the PositionableAudioSource.

## ◆ ~PositionableAudioSource()

juce::PositionableAudioSource::~PositionableAudioSource | ( |  | ) |
| override default

Destructor

## 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::BufferingAudioSource, juce::AudioTransportSource, and juce::AudioFormatReaderSource.

Referenced by juce::AudioTransportSource::getNextAudioBlock(), and juce::AudioTransportSource::getNextReadPosition().

## ◆ getTotalLength()

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

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

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

Referenced by juce::AudioTransportSource::getNextAudioBlock(), juce::BufferingAudioSource::getTotalLength(), and juce::AudioTransportSource::getTotalLength().

## ◆ isLooping()

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

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

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

Referenced by juce::AudioTransportSource::getNextAudioBlock(), juce::BufferingAudioSource::isLooping(), and juce::AudioTransportSource::isLooping().

## ◆ setLooping()

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

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

Reimplemented in juce::AudioFormatReaderSource.

Definition at line 73 of file juce_PositionableAudioSource.h.

## ◆ 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::BufferingAudioSource, juce::AudioTransportSource, and juce::AudioFormatReaderSource.

Referenced by juce::AudioTransportSource::setNextReadPosition(), and juce::AudioTransportSource::setSource().
