Detailed Description

Simple player for an Node.

This simply iterate all the nodes attempting to process them in a single thread.

Constructor & Destructor Documentation

NodePlayer()

tracktion::graph::NodePlayer::NodePlayer	(	std::unique_ptr< Node >	nodeToProcess,
		PlayHeadState *	playHeadStateToUse = nullptr
	)

Creates an NodePlayer to process a Node.

Member Function Documentation

getNode()

Node * tracktion::graph::NodePlayer::getNode

(

)

Returns the current Node.

Definition at line 34 of file tracktion_NodePlayer.h.

getSampleRate()

double tracktion::graph::NodePlayer::getSampleRate

(

)

const

Definition at line 113 of file tracktion_NodePlayer.h.

prepareToPlay() [1/2]

void tracktion::graph::NodePlayer::prepareToPlay	(	double	sampleRateToUse,
		int	blockSizeToUse
	)

Prepares the current Node to be played.

Definition at line 61 of file tracktion_NodePlayer.h.

prepareToPlay() [2/2]

std::unique_ptr< NodeGraph > tracktion::graph::NodePlayer::prepareToPlay	(	std::unique_ptr< Node >	node,
		NodeGraph *	oldGraph,
		double	sampleRateToUse,
		int	blockSizeToUse
	)

Prepares a specific Node to be played and returns all the Nodes.

Definition at line 74 of file tracktion_NodePlayer.h.

process()

int tracktion::graph::NodePlayer::process

(

const 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.

Definition at line 88 of file tracktion_NodePlayer.h.

processPostorderedNodes()

int tracktion::graph::NodePlayer::processPostorderedNodes	(	NodeGraph &	graphToProcess,
		const Node::ProcessContext &	pc
	)

Definition at line 118 of file tracktion_NodePlayer.h.

processPostorderedNodesSingleThreaded()

static int tracktion::graph::NodePlayer::processPostorderedNodesSingleThreaded ( NodeGraph &  nodeGraph, const Node::ProcessContext &  pc  )

staticprotected

Processes a group of Nodes assuming a postordering VertexOrdering.

If these conditions are met the Nodes should be processed in a single loop iteration.

setNode() [1/2]

void tracktion::graph::NodePlayer::setNode

(

std::unique_ptr< Node >

Sets the Node to process.

Definition at line 42 of file tracktion_NodePlayer.h.

setNode() [2/2]
