heronarts.lx.parameter

Class LXVirtualParameter

java.lang.Object

heronarts.lx.parameter.LXVirtualParameter

All Implemented Interfaces:

LXPath, LXParameter

public abstract class LXVirtualParameter
extends Object
implements LXParameter

A virtual parameter is one that wraps or forwards to another real parameter. Typically this is done in situations in which the parameter to forward to varies based on some other contextual action or UI, for instance a virtual knob that maps to whatever pattern is currently active. This type of parameter is not listenable, since the underlying parameter is dynamic.
