Examples of org.openstreetmap.josm.io.CachedFile

org.openstreetmap.josm.io.CachedFile
Downloads a file and caches it on disk in order to reduce network load. Supports URLs, local files, and a custom scheme (resource:) to get resources from the current *.jar file. (Local caching is only done for URLs.)
The mirrored file is only downloaded if it has been more than 7 days since last download. (Time can be configured.)
The file content is normally accessed with {@link #getInputStream()}, but you can also get the mirrored copy with {@link #getFile()}.
