Examples of org.dspace.content.Item$MetadataCache

org.dspace.content.Item
Class representing an item in DSpace.
This class holds in memory the item Dublin Core metadata, the bundles in the item, and the bitstreams in those bundles. When modifying the item, if you modify the Dublin Core or the "in archive" flag, you must call update for the changes to be written to the database. Creating, adding or removing bundles or bitstreams has immediate effect in the database. @author Robert Tansley @author Martin Hald @version $Revision$
