org.openstreetmap.josm.gui.layer.Layer
A layer encapsulates the gui component of one dataset and its representation. Some layers may display data directly imported from OSM server. Other only display background images. Some can be edited, some not. Some are static and other changes dynamically (auto-updated). Layers can be visible or not. Most actions the user can do applies only on selected layers. The available actions depend on the selected layers too. All layers are managed by the MapView. They are displayed in a list to the right of the screen. @author imi
