Class MetaObjectCache

java.lang.Object
  se.datadosen.jalbum.MetaObjectCache

All Implemented Interfaces:

java.io.Serializable, java.util.Map

public class MetaObjectCache
extends java.lang.Object
implements java.util.Map, java.io.Serializable

The purpose of this class is to implement a lazy-fetch behavour for the previously extremely big "meta" object (around 6500 bytes) in order to save RAM during album generation as JAlbum stores all metadata gathered during album generation. This object currently only caches one single meta object in a static variable that may change. This class is supposed to be thread safe.
