com.bbn.openmap.omGraphics.OMGeometryList
This class encapsulates a List of OMGeometries. It's an OMGraphic, so it contains information on how to draw them. It's also a subclass to the OMGraphicList, and relies on many OMGraphicList methods.
The OMGeometryList assumes that all OMGeometries on it should be rendered the same - same fill color, same edge color and stroke, and will create one java.awt.Shape object from all the projected OMGeometries for more efficient rendering. If your individual OMGeometries have independing rendering characteristics, use the OMGraphicList and OMGraphics.
Because the OMGeometryList creates a single java.awt.Shape object for all of its contents, it needs to be generated() if an OMGeometry is added or removed from the list. If you don't regenerate the OMGeometryList, the list will iterate through its contents and render each piece separately.
