void MayaFlux::Nodes::Generator::Phasor::notify_tick ( double  value)
overrideprotectedvirtual

Notifies all registered callbacks about a new sample.

Parameters
valueThe newly generated sample

This method is called internally whenever a new sample is generated, creating the appropriate context and invoking all registered callbacks that should receive notification about this sample.

Implements MayaFlux::Nodes::Node.
