public abstract class Shape
extends Object
implements Locatable2D, Serializable, Cloneable, com.anylogic.engine.internal.Child, SVGElement, LevelElement

The base class for all graphical shapes and also for all controls.
Shapes allow direct programmatic control, i.e. you can change the properties of the shapes explicitly by calling their methods, e.g. setWidth(). Shape also has reference to the group they belong.

Description copied from interface: SVGElement

This method is internal and shouldn't be called by user.
it may be removed/renamed in future.
Updates SVG properties of the element that are then sent to the rendering client. If the element is not yet in the SVG scene, generates "C" command, if it is there, but some properties are out of date, generates "U" command. If SVG drawing of this element is not needed because of public only settings, or permanently not needed, or not supported yet, returns false and does nothing.

Specified by:

updateSVGProperties in interface SVGElement

Parameters:

output - the list of commands to add to

drawMode - TODO

publicOnly - drawing context: if true, only shapes that are marked as public only are updated

owner - the SVG element that serves as a container for this element

elbehind - the SVG element behind this one, or null if none or if order is irrelevant

Returns:

the actual owner this element has been added to or null if element is not drawn (e.g. drawing of this element is not needed because of public only settings, permanently not needed or not supported - hence SVG id is not set). The actual owner may differ from the given owner when the svg element is added to a different place (e.g. GIS map).
