Class BrowseEngine

java.lang.Object

org.dspace.browse.BrowseEngine

public class BrowseEngine
extends java.lang.Object

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
