Examples of org.dspace.content.Bundle

org.dspace.content.Bundle
Class representing bundles of bitstreams stored in the DSpace system
The corresponding Bitstream objects are loaded into memory. At present, there is no metadata associated with bundles - they are simple containers. Thus, the update method doesn't do much yet. Creating, adding or removing bitstreams has instant effect in the database. @author Robert Tansley @version $Revision: 4309 $
