Hello Actually if you look at my implementation, i use that List.sublist() method.
It's a little pain to use it to split because you must always take care of an out of bound... IMHO, people do not really like to play with array/list indexes... If they just want to split a big list of a couple of small sublists, they probably do not like to have to deal with calculating the good index positions, they just want the list to be splitted :) I've looked at some guava classes but wasn't able to find anything to do this: a convenient way to split a list 2011/8/18 David Karlsen <davidkarl...@gmail.com> > Guava also has a lot of handy classes for working on collections. > > 2011/8/18 Simone Tripodi <simonetrip...@apache.org> > > > Salut Sébastien, > > wouldn't the List#subList(int, int)[1] method be helpful for your > purposes? > > HTH, > > Simo > > > > [1] > > > http://download.oracle.com/javase/1.5.0/docs/api/java/util/List.html#subList(int > > , > > int) > > > > > > http://people.apache.org/~simonetripodi/ > > http://www.99soft.org/ > > > > > > > > On Thu, Aug 18, 2011 at 2:26 PM, Sébastien Lorber > > <lorber.sebast...@gmail.com> wrote: > > > Hello, > > > > > > > > > It's not the first time i have to split a big list of hibernate > entities > > > ID's to sublists of 100 items for exemple so that i could load all > these > > > entities 100 in a single request (with a "where id in (<id sublist>") > > > > > > Thus I want to iterate easily on sublists of a list, with the > possibility > > to > > > give the sublist a size... > > > I though i would find the tool in apache collections but i didn't find > > it. > > > Perhaps i've missed the class... > > > > > > > > > > > > If there's no tool to do that yet, i think it would be great to make > one > > in > > > apache collections. > > > > > > The kinda simple implementation i use at work is the following: > > > http://pastebin.com/CRitkWTG > > > > > > > > > And you use it like that: > > > > > > // We load vehicles 100 by 100 > > > for ( List<String> idSublist : new > > > SublistIterable<String>(allIds,100) ) { > > > List<Vehicle> vehiclesSublist = > > vehicleDAO.findByIds(idSublist); > > > // blablabla > > > } > > > > > > > --------------------------------------------------------------------- > > To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org > > For additional commands, e-mail: dev-h...@commons.apache.org > > > > > > > -- > -- > David J.
