public abstract class EnumControl extends Control
An EnumControl provides control over a set of discrete possible values, each represented by an object. In a graphical user interface, such a control might be represented by a set of buttons, each of which chooses one value or setting. For example, a reverb control might provide several preset reverberation settings, instead of providing continuously adjustable parameters of the sort that would be represented by FloatControl objects.

Controls that provide a choice between only two settings can often be implemented instead as a BooleanControl, and controls that provide a set of values along some quantifiable dimension might be implemented instead as a FloatControl with a coarse resolution. However, a key feature of EnumControl is that the returned values are arbitrary objects, rather than numerical or boolean values. This means that each returned object can provide further information. As an example, the settings of a REVERB control are instances of ReverbType that can be queried for the parameter values used for each setting.
