Examples of org.openstreetmap.josm.command.Command

org.openstreetmap.josm.command.Command
Classes implementing Command modify a dataset in a specific way. A command is one atomic action on a specific dataset, such as move or delete. The command remembers the {@link OsmDataLayer} it is operating on. @author imi
