Description

Setup, event handler, and teardown methods to be implemented by stateful node classes.

Functions
struct nodeInstanceData *	nodeInstanceInit (...)
	Called when a new instance of the node class is created.

void	nodeInstanceEvent (...)
	Called for every push this node instance receives.

void	nodeInstanceFini (struct nodeInstanceData *const context)
	Called when the specified node instance is no longer needed.

Function Documentation

void nodeInstanceEvent ( ... )

Called for every push this node instance receives.

Parameter decorations should include at least:

Parameter decorations may include:

void nodeInstanceFini ( struct nodeInstanceData *const context )

Called when the specified node instance is no longer needed.

The implementation should free() whatever instance data was allocated in nodeInstanceInit().

struct nodeInstanceData* nodeInstanceInit ( ... )

read

Called when a new instance of the node class is created.

The implementation should malloc(), initialize, and return whatever instance data is required.

Parameter decorations may include:

VuoOutputGenerator — Stateful nodes may store references to generator functions in their instance data, in order to generate events at any time.
