Class BooleanControl

java.lang.Object
javax.sound.sampled.Control
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.

    • BooleanControl

      protected BooleanControl(BooleanControl.Type type, boolean initialValue, String trueStateLabel, String falseStateLabel)
      Constructs a new boolean control object with the given parameters.
      Parameters:
      type - 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)
      Constructs a new boolean control object with the given parameters. The labels for the true and false states default to "true" and "false".
      Parameters:
      type - the type of control represented by this float control object
      initialValue - 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

      public String getStateLabel(boolean state)
      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" for false

    • toString

      public String toString()
      Returns a string representation of the boolean control.
      Overrides:
      toString in class Control
      Returns:
      a string representation of the boolean control
