Examples of ItemCounter

org.dspace.browse.ItemCounter
This class provides a standard interface to all item counting operations for communities and collections. It can be run from the command line to prepare the cached data if desired, simply by running: java org.dspace.browse.ItemCounter It can also be invoked via its standard API. In the event that the data cache is not being used, this class will return direct real time counts of content. @author Richard Jones
