public abstract class BooleanControl extends Control
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 MUTE
control to
silence the line's audio.
As with other Control
subclasses, a method is provided that returns
string labels for the values, suitable for display in the user interface.
