Examples of org.dspace.content.Bitstream

org.dspace.content.Bitstream
Class representing bitstreams stored in the DSpace system.
When modifying the bitstream metadata, changes are not reflected in the database until update is called. Note that you cannot alter the contents of a bitstream; you need to create a new bitstream. @author Robert Tansley @version $Revision: 4657 $
