Examples of org.openstreetmap.josm.data.osm.ChangesetCache

org.openstreetmap.josm.data.osm.ChangesetCache
ChangesetCache is global in-memory cache for changesets downloaded from an OSM API server. The unique instance is available as singleton, see {@link #getInstance()}. Clients interested in cache updates can register for {@link ChangesetCacheEvent}s using {@link #addChangesetCacheListener(ChangesetCacheListener)}. They can use {@link #removeChangesetCacheListener(ChangesetCacheListener)} to unregister ascache event listener. The cache itself listens to {@link java.util.prefs.PreferenceChangeEvent}s. It clears itself if the OSM API URL is changed in the preferences. {@link ChangesetCacheEvent}s are delivered on the EDT.
