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 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.

Constructs a new boolean control object with the given parameters.
Parameters:
the - type of control represented this float control object
initialValue - the initial control value
trueStateLabel - the label for the state represented by true, such as "true" or "on."
falseStateLabel - the label for the state represented by false, such as "false" or "off."

BooleanControl

protected BooleanControl(BooleanControl.Type type,
                         boolean initialValue)

Parameters:
the - type of control represented by this float control object
initialValue - the initial control value

Parameters:
value - desired new value.

getValue

public boolean getValue()
