public abstract class BooleanControl extends Control
A BooleanControl
provides the ability to switch between two possible settings that affect a line's audio. The settings are boolean values (true
and false
). A graphical user interface might represent the control by a two-state button, an on/off switch, two mutually exclusive buttons, or a checkbox (among other possibilities). For example, depressing a button might activate a
control to silence the line's audio. MUTE
As with other
subclasses, a method is provided that returns string labels for the values, suitable for display in the user interface.Control
