javax.sound.sampled.BooleanControl
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.

type
- the type of control represented this float control objectinitialValue
- the initial control valuetrueStateLabel
- the label for the state represented bytrue
, such as "true" or "on"falseStateLabel
- the label for the state represented byfalse
, such as "false" or "off"
-
BooleanControl
Constructs a new boolean control object with the given parameters. The labels for thetrue
andfalse
states default to "true" and "false".- Parameters:
type
- the type of control represented by this float control objectinitialValue
- the initial control value
-
-
Method Details
-
setValue
public void setValue(boolean value)Sets the current value for the control. The default implementation simply sets the value as indicated. Some controls require that their line be open before they can be affected by setting a value.- Parameters:
value
- desired new value
-
getValue
public boolean getValue()Obtains this control's current value.- Returns:
- current value
-
getStateLabel
Obtains the label for the specified state.- Parameters:
state
- the state whose label will be returned- Returns:
- the label for the specified state, such as "true" or "on" for
true
, or "false" or "off" forfalse
-
