Public Member Functions
	Stream (std::shared_ptr< const Context > context, std::shared_ptr< Device > device, const StreamParameters &params={})
	Construct stream.

Getters and setters
virtual bool	GetIsActive () const
	Tell whether the stream participates in I/O. By default returns the last value set by SetIsActive(). Initial value is true.

OSStatus	SetIsActive (bool isActive)
	Activate or deactivate stream. Invokes SetIsActiveImpl() and NotifyPropertyChanged().

virtual Direction	GetDirection () const
	Get stream direction. By default returns corresponding field of StreamParameters.

virtual UInt32	GetTerminalType () const
	Get terminal type. By default returns kAudioStreamTerminalTypeMicrophone if GetDirection() returns Direction::Input, and kAudioStreamTerminalTypeSpeaker if it return Direction::Output.

virtual UInt32	GetStartingChannel () const
	Absolute channel number for the first channel in the stream. For example, if a device has two output streams with two channels each, then the starting channel number for the first stream is 1 and thus starting channel number for the second stream is 3. By default returns StreamParameters::StartingChannel.

UInt32	GetChannelCount () const
	Get number of channels in stream. Return value is based on GetPhysicalFormat().

Float64	GetSampleRate () const
	Get stream sample rate. Return value is based on GetPhysicalFormat().

virtual UInt32	GetLatency () const
	Get any additional presentation latency the stream has. This latency is added to the device latency. By default returns value last set with SetLatencyAsync(). Initial value is StreamParameters::Latency.

OSStatus	SetLatencyAsync (UInt32 latency)

OSStatus	SetPhysicalFormatAsync (AudioStreamBasicDescription format)
	Set current format of the stream. Requests HAL to asynchronously invoke SetPhysicalFormatImpl(). Fails if format is not present in GetAvailablePhysicalFormats(), which by default returns only one format, provided during initialization. If you want to make your stream supporting multiple formats, you typically need to override both of these methods.

virtual std::vector< AudioStreamRangedDescription >	GetAvailablePhysicalFormats () const
	Get list of supported physical formats. Empty list means that any format is allowed. By default returns the last value set by SetAvailablePhysicalFormatsAsync(). If nothing was set, return a single-element list with the format returned by GetPhysicalFormat().

For devices that don't override the mix operation, the virtual format has to be the same as the physical format. By default returns value set by last SetVirtualFormatAsync() call. Initial value is StreamParameters::Format.

OSStatus	SetVirtualFormatAsync (AudioStreamBasicDescription format)
	Set current virtual format of the stream. Requests HAL to asynchronously invoke SetVirtualFormatImpl().

Detailed Description

Audio stream object.

Stream is part of a Device representing a source (input stream) or a destination (output stream) for samples. Clients connected to the device can read from its input streams and write to its output streams.

Each stream can have its own format, latency, and other parameters.

Stream does not do I/O by its own. Instead, it provides ApplyProcessing() method, which is invoked by ReaderWriter (in its default implementation).

Default implementation of Stream::ApplyProcessing() just invokes corresponding methods on attached VolumeControl and MuteControl objects, which you can set using AttachVolumeControl() and AttachMuteControl().
