Class Graphic

java.lang.Object
  com.esri.core.map.Graphic

All Implemented Interfaces:

Serializable

public class Graphic
extends Object
implements Serializable

The Graphic class is used to represent a feature that can have any of the following types:

• Geometry
• Symbol
• attributes
• InfoTemplate

Graphic objects are immutable, which means its state cannot change after construction. When a Graphic object is added to a GraphicsLayer via the GraphicsLayer.addGraphic(Graphic) method, this method returns a unique ID (UID) which you can then use to reference the added graphic for subsequent operations. Graphic objects are stateless so there is no guarantee that a feature in the GraphicsLayer exists after the request for the Graphic object is completed.

Graphic objects can be displayed, altered and removed using a GraphicsLayer (see the GraphicsLayer class for more details)
