public interface Actuator<S extends Sensor>

A controller that activates and directs a stage light according to the properties of an assigned sensor. Lights and sensors may exist in any number. Each coordinated light/sensor pair is mediated by an assigned actuator. The typical lines of visibility are thus:

    Light  ←  Actuator  →  Sensor

One purpose of this arrangement is to speed light direction by having the actuator pre-construct the directional data for its sensor and cache it for repeated use. Where this optimization is not required, the implementation of the actuator may be folded into the light, a single instance for all sensors:

   (Light, Actuator)  →  Sensor

Method Summary

Methods

Modifier and Type	Method and Description
void	changed(S sensor) Responds to a change in the sensor's properties.
Light<S>	light() The stage light that is directed.
void	out(S sensor) Responds to the user's point leaving the sensor.
void	over(S sensor) Responds to the user's point entering the sensor.
