notify_tick()

void MayaFlux::Nodes::Input::InputNode::notify_tick ( double  value )

overrideprotectedvirtual

Notify callbacks (minimal for InputNode)

InputNodes fire callbacks sparingly - the input event IS the notification. Override if you need per-sample callbacks (rare for input).

Implements MayaFlux::Nodes::Node.

Reimplemented in MayaFlux::Nodes::Input::MIDINode.
