If you are interested in doing queries on Java objects, I'll add my 2 cents about JDO's query language. JDOQL supports queries against Java objects, using your Java classes as its data model, and using Java operators in the query language.
But I am assuming you just want to do queries on Java objects in memory, without a database involved. Well... the JDO reference implementation, which is free and downloadable in source form, actually does support queries against objects in memory. It also supports queries to the datastore, but it should be feasible with a little bit of work to get it to solely work with objects in memory. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Kevin Chipalowsky > Sent: Thursday, September 16, 2004 9:41 AM > To: [EMAIL PROTECTED] > Subject: Re: [Juglist] JXPath > > > I used JXPath within a project about nine months ago. > I found it easy to use, and despite my concerns, > performance wasn't really a problem. > > However, I would advise against using it for large > projects, because code that uses JXPath is hard to > maintain.
