The geometry classes are intended to pull the object location data out of the OMGraphics. If you have a bunch of OMGraphics that are all rendered with common attributes, you can create a bunch of OMGeometry objects to plavce in a OMGeometryList that will render them all alike.
The BasicGeometry can hold attributes. Traditionally, there has been an appObject (Application Object) that could be set in the OMGeometry/OMGraphic to maintain a pointer for additional infomration about the shape. This has been modified so that an attribute Map can be maintained for the BasicGeometry to let it hold on to a bunch of organized attributes. To maintain backward compatibility, the setAppObject() and getAppObject() methods have been modified to manage a java.util.Map along with any Objects stored in the appObject. Using the setAppObject() and getAppObject() methods in conjunction with other attributes will cause that object to be stored in the attribute Map under the APP_OBJECT_KEY Map key. @see PolygonGeometry @see PolylineGeometry @see com.bbn.openmap.omGraphics.OMGeometryList @see Projection
