Hi,
I was wondering how the datamodel gets populated. Are all entries retrieved
right away? I display information page-wise, and sometimes there could be 30-40
pages of data, so is the actual object only loaded into memory when I access it
or is everything that's in the datamodel in memory? Should I manually use
limit-queries (which I didn't think were supported [i.e. limit (20,80)] ) or is
it feasible to always use the subList?
I have right now the following
private List everything;
@DataModel
List subset;
initially I populate the list everything with the em.query("from stuff")...
when the next() is called I do
public void() {
subset = everything.subList(pos,pos+size);
}
Is there anything wrong with that approach? Anything I could improve? The
reason why I am asking is that sometimes I have high response times, which I
have yet to understand..
Thanks,
joey
