org.dspace.browse.BrowseEngine
This class does most of the actual grunt work of preparing a browse result. It takes in to a couple of available methods (depending on your desired browse type) a BrowserScope object, and uses this to produce a BrowseInfo object which is sufficient to describe to the User Interface the results of the requested browse @author Richard Jones
