Detailed Description

Plays back a Node with PlayHeadState and ProcessState.

Constructor & Destructor Documentation

TracktionNodePlayer() [1/3]

tracktion::engine::TracktionNodePlayer::TracktionNodePlayer

(

ProcessState &

processStateToUse

)

Creates an NodePlayer to process a Node.

		tracktion::graph::LockFreeMultiThreadedNodePlayer::ThreadPoolCreator	poolCreator,
		juce::AudioWorkgroup	audioWorkgroup = {}
	)

Creates an NodePlayer to process a Node.

setNumThreads()

void tracktion::engine::TracktionNodePlayer::setNumThreads

(

size_t

numThreads

)

Sets the number of threads to use for rendering.

This can be 0 in which case only the process calling thread will be used for processing. N.B. this will pause processing whilst updating the threads so there will be a gap in the audio.

getNode()

tracktion::graph::Node * tracktion::engine::TracktionNodePlayer::getNode

)

References tracktion::graph::LockFreeMultiThreadedNodePlayer::getNode().

setNode() [1/2]

void tracktion::engine::TracktionNodePlayer::setNode

(

References tracktion::graph::LockFreeMultiThreadedNodePlayer::setNode().

setNode() [2/2]

prepareToPlay()

void tracktion::engine::TracktionNodePlayer::prepareToPlay	(	double	sampleRateToUse,
		int	blockSizeToUse
	)

References tracktion::graph::LockFreeMultiThreadedNodePlayer::prepareToPlay().

process()

int tracktion::engine::TracktionNodePlayer::process

(

const tracktion::graph::Node::ProcessContext &

pc

)

Processes a block of audio and MIDI data.

Returns the number of times a node was checked but unable to be processed.

clearNode()

void tracktion::engine::TracktionNodePlayer::clearNode

(

)

Clears the Node currently playing.

(

)

const

Returns the current sample rate.
