An ARObject is an abstract class which must not be instantiated directly.
It provides basic methods and properties required for the objects rendered in the AR scene.
ARObjects are somehow registered in the real world, either with geo coordinates (GeoObject) or with visual trackable objects (Trackable2DObject). They also have Drawables attached to it, which are used to represent the ARObject on the screen.

Destroys the object.
Adds Drawables to the ARObject in the camera.
drawableDrawable | Drawable
The drawable(s) that should be added to the camera. Can either be a single Drawable, or an Array of Drawables.
The position where the Drawable should be added in the array. If not specified, the Drawable will be added at the end of the array. Must be a whole number.
Removes Drawables from the ARObject in the cam.
drawable|positionDrawable | [Drawable] | Number
When a single Drawable or an Array of Drawables is given, these Drawables will be removed from the array. When an integer is given, the Drawable at the specified position will be removed.
Returns the current visibility state of the ARObject. An ARObject is defined visible when at least one of the ARObject's locations (geolocations or visual tracker) is projected onto a screen coordinate which is currently visible on the screen.
Whether the ARObject is currently visible on the screen (true) or invisble (false).
Indicates if the object has already been destroyed.
The Drawables which will be used to represent the ARObject
in the camera view.
Drawables in the array will be printed starting with the Drawable at position 0, causing Drawables at later indices to overlap the previously drawn Drawables.
The array content should not be manipulated via the  operator, as it cannot be guaranteed that the changes will be propagated through to the native application. The property should only be manipulated with arobject.drawables.addCamDrawable() and arobject.drawables.removeCamDrawable(), or directly set with arobject.drawables.cam = new Array(...);.
A boolean flag to enable or disable the ARObject.
Drawables of different ARObjects might overlap. In this case, renderingOrder defines the rendering order of the Drawables of the ARObject.
ARObjects with higher renderingOrder values cause their Drawables to be drawn on top of the Drawables of ARObjects with lower renderingOrder values.
In case two ARObjects have set the same renderingOrder, the Drawables are rendered based on the distance, causing objects closer to the user to
overlap objects further away.
For example, If you want to bring Drawables of a certain ARObject to the very front, set the renderingOrder value of the corresponding ARObject to a very high value.
For the printing order of Drawables within the same ARObject, refer to Drawable2D.zOrder.
Must be a whole number.
Will be executed when any of the ARObject's Drawables have been clicked,
and none of the clicked Drawables's onClick() triggers (might also be referenced by another ARObject)
have been set to quit the click chain. ARObject.onClick() will be executed after any Drawable.onClick() triggers have
In case multiple ARObjects are hit by the click, the order of the execution is defined by the distance of the ARObject to the user, with the closest ARObject's click trigger executed first.
The return value of the function determines if, after the onClick()-Function was executed for this ARObject, the queue shall continue to execute onClick() for the next ARObject in the queue. In case the last ARObject in the queue still requests to continue the click-queue, context.onScreenClick() will be executed.
The return value of the function decides what to do next. If false, the click-queue should not stop with this ARObject. Thus, the next ARObject's onClick() function will be executed. This is the default value in case no return value is set or the function is not defined for this ARObject. If true, the queue-execution will stop at the current ARObject, underlying ARObjects will not receive onClick() calls.
The trigger will fire when the ARObject's visibility has
changed from invisible to visible.
The trigger is null by default, and will thus result in no action executed when the trigger fires. A developer can add custom functionality by assigning a custom function to onEnterFieldOfVision.
In case of a Trackable2DObject holds the name of the recognized target. Used in combination with wildcards for targetName.
Will be executed when the ARObject's visibility has changed
from visible to invisible.
The trigger is null by default, and will thus result in no action executed when the trigger fires. A developer can add custom functionality by assigning a custom function to onExitFieldOfVision.
In case of a Trackable2dObject this will hold the name of the target that exited the field of vision.
