## Package com.bbn.openmap.plugin.graphicLoader Description

The GraphicLoader PlugIn package is designed to provide support for GraphicLoaders, which in turn are objects that need to drive changes in OMGraphics over a map. The GraphicLoader is an object that manages OMGraphics and their positions, and sends an OMGraphicList to its receiver when they need to be updated.

The package consists of a GraphicLoaderPlugIn, which is a PlugIn that accepts graphics from another object, called the GraphicLoader. The GraphicLoader is an object with a timer that manages these location objects. The GraphicLoaderConnector is an object that should be added to the MapHander - when it finds a GraphicLoader in the MapHandler, it will automatically create a GraphicLoaderPlugIn for it, and will either give the GraphicLoaderPlugIn to the LayerHandler if it knows about one, or give the GraphicLoaderPlugIn to the MapHandler so it can be found by the LayerHandler later.

To add a GraphicLoader to the OpenMap application, you can do it several ways:

- You can create a specific GraphicLoaderPlugIn that creates its own GraphicLoader, and initializes it accordingly. You would add the GraphicLoaderPlugIn to the openmap.layers property in the openmap.properties file.
- You can create a GraphicLoaderPlugIn by adding an entry to the openmap.layer property in the openmap.properties file, and define what kind of GraphicLoader to create in the properties for the GraphicLoaderPlugIn.
- You can add a com.bbn.openmap.plugin.graphicLoader.GraphicLoaderConnector to the openmap.components property, and then add the GraphicLoader to the openmap.components property as well. The GraphicLoaderConnector will find the GraphicLoader, and create a GraphicLoaderPlugIn/PlugInLayer for the GraphicLoader and add it to the LayerHandler on top of the map.
