The GesturePhase class is an enumeration class of constant values for use with the GestureEvent, PressAndTapGestureEvent, and TransformGestureEvent classes. Use these values to track the beginning, progress, and end of a touch gesture (such as moving several fingers across a touch enabled screen) so your application can respond to individual stages of user contact. Some gestures (swipe and two-finger tap gestures) do not have multiple phases, and set the event object phase property to all.

public static const ALL:String = "all"

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10.1, AIR 2

A single value that encompasses all phases of simple gestures like two-finger-tap or swipe. For gestures that set the event object phase property to all (swipe and two-finger tap gestures), the phase value is always all once the event is dispatched.

TransformGestureEventExample.as

The following example shows event handling for the GESTURE_ROTATE events. While the user performs a rotation gesture on the touch-enabled device, mySprite rotates and myTextField populates with the current phase.
Multitouch.inputMode = MultitouchInputMode.GESTURE;

var mySprite = new Sprite();
mySprite.addEventListener(TransformGestureEvent.GESTURE_ROTATE , onRotate );
mySprite.graphics.beginFill(0x336699);
mySprite.graphics.drawRect(0, 0, 100, 80);
var myTextField = new TextField();
myTextField.y = 200;
addChild(mySprite);
addChild(myTextField);

function onRotate(evt:TransformGestureEvent):void {

    evt.target.rotation -= 45;

    if (evt.phase==GesturePhase.BEGIN) {
        myTextField.text = "Begin";
    }
    if (evt.phase==GesturePhase.UPDATE) {
        myTextField.text = "Update";
    }
    if (evt.phase==GesturePhase.END) {
        myTextField.text = "End";
    }
}
