Package nl.colorize.multimedialib.scene

Class MediaCache

java.lang.Object

nl.colorize.multimedialib.scene.MediaCache

All Implemented Interfaces:

MediaLoader

public class MediaCache
extends java.lang.Object
implements MediaLoader

Wrapper around MediaLoader that caches all loaded media files. If the same file is requested multiple times, the version from the cache is returned. Obviously, it is also possible to just load the file once and then use the reference, but in practice this tends to be occasionally forgotten, so automated caching will lead to better performance for such situations.
