How to use the @egjs/axes.DIRECTION_ALL function in @egjs/axes

connect(observer) {
		// User intetened direction
		this._userDirection = this._direction;

		// In VR Mode, Use ALL direction if direction is not none
		// Because horizontal and vertical is changed dynamically by screen rotation.
		// this._direction is used to initialize hammerjs
		if (this._useRotation && (this._direction & Axes.DIRECTION_ALL)) {
			this._direction = Axes.DIRECTION_ALL;
		}

		super.connect(observer);
