Enum GestureAction

java.lang.Object

java.lang.Enum<GestureAction>

com.otaliastudios.cameraview.GestureAction

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<GestureAction>

public enum GestureAction
extends java.lang.Enum<GestureAction>

Gestures actions are actions over camera controls that can be mapped to certain gestures over the screen, using XML attributes or CameraView.mapGesture(Gesture, GestureAction). Not every gesture can control a certain action. For example, pinch gestures can only control continuous values, such as zoom or AE correction. Single point gestures, on the other hand, can only control point actions such as focusing or capturing a picture.

Method Detail

values

public static GestureAction[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (GestureAction c : GestureAction.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static GestureAction valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
