public final class NewGroupsOrNewsQuery
extends Object
The NewGroupsOrNewsQuery class is used to issue NNTP NEWGROUPS and NEWNEWS queries, implemented by listNewNewsGroups and listNewNews respectively. It prevents you from having to format date, time, distribution, and newgroup arguments.

You might use the class as follows:

 query = new NewsGroupsOrNewsQuery(new GregorianCalendar(97, 11, 15), false);
 query.addDistribution("comp");
 NewsgroupInfo[] newsgroups = client.listNewgroups(query);
 
This will retrieve the list of newsgroups starting with the comp. distribution prefix created since midnight 11/15/97.
