Examples of com.bbn.openmap.omGraphics.OMGraphicList

com.bbn.openmap.omGraphics.OMGraphicList
This class encapsulates a List of OMGraphics.
There are several things that this list does that make it better that any ol' List. You can make several common OMGraphic modification calls on the list, and the list handles the iteration and changing of all the graphics while taking into account a travese order.
An additional benefit is that because the OMGraphicList extends OMGraphic it can contain other instances of OMGraphicList. This way you can manage groupings of graphics, (for instance, an OMGraphicList of OMGraphicLists which each have an OMRaster and OMText).
Many methods, such as generate() and findClosest() traverse the items in the GraphicsList recursively. The direction that the list is traversed is controlled by then traverseMode variable. The traverseMode mode lets you set whether the first or last object added to the list (FIRST_ADDED_ON_TOP or LAST_ADDED_ON_TOP) is drawn on top of the list and considered first for searches.
