Inheritance diagram for tracktion::graph::ForwardingNode:

Public Member Functions
	ForwardingNode (tracktion::graph::Node *inputNode, std::optional< size_t > nodeIDToUse={})

	ForwardingNode (std::shared_ptr< tracktion::graph::Node > inputNode, std::optional< size_t > nodeIDToUse={})

tracktion::graph::NodeProperties	getNodeProperties () override
	Should return the properties of the node.

std::vector< tracktion::graph::Node * >	getDirectInputNodes () override
	Should return all the inputs directly feeding in to this node.

bool	isReadyToProcess () override
	Should return true when this node is ready to be processed.

void	process (ProcessContext &pc) override
	Called when the node is to be processed.

Public Member Functions inherited from tracktion::graph::Node
	Node ()=default

virtual	~Node ()=default

void	initialise (const PlaybackInitialisationInfo &)
	Call once after the graph has been constructed to initialise buffers etc.

void	prepareForNextBlock (juce::Range< int64_t > referenceSampleRange)
	Call before processing the next block, used to reset the process status.

void	process (choc::buffer::FrameCount numSamples, juce::Range< int64_t > referenceSampleRange)
	Call to process the node, which will in turn call the process method with the buffers to fill.

bool	hasProcessed () const
	Returns true if this node has processed and its outputs can be retrieved.

AudioAndMidiBuffer	getProcessedOutput ()
	Returns the processed audio and MIDI output.

virtual TransformResult	transform (TransformOptions &)
	Called after construction to give the node a chance to modify its topology.

virtual std::vector< Node * >	getInternalNodes ()
	Can return Nodes that are internal to this Node but don't make up the main graph constructed from getDirectInputNodes().

void	retain ()
	Retains the buffers so they won't be deallocated after the Node has processed.

void	release ()
	Releases the buffers allowing internal storage to be deallocated.

virtual size_t	getAllocatedBytes () const

void	enablePreProcess (bool)

Additional Inherited Members

Protected Member Functions inherited from tracktion::graph::Node
virtual void	prepareToPlay (const PlaybackInitialisationInfo &)
	Called once before playback begins for each node.

virtual void	prefetchBlock (juce::Range< int64_t >)
	Called before once on all Nodes before they are processed.

virtual void	preProcess (choc::buffer::FrameCount, juce::Range< int64_t >)
	Called when the node is to be processed, just before process.

void	setOptimisations (NodeOptimisations)
	This can be called to provide some hints about allocating or playing back a Node to improve efficiency.

void	setBufferViewToUse (Node *sourceNode, const choc::buffer::ChannelArrayView< float > &)
	This can be called during prepareToPlay to set a BufferView to use which can improve efficiency.

void	setAudioOutput (Node *sourceNode, const choc::buffer::ChannelArrayView< float > &)
	This can be called during your process function to set a view to the output.
