Subject Re: Fetching Specified "Raw Rows" with SelectQuery
Date Sun, 25 Apr 2010 12:40:59 GMT
Hi Ari;

Aha! (penny drops) -- ok that is the behaviour I'm after.  Thanks to both of you for talking
this through.  I've written some material to go at the top of "SelectQuery" javadoc to confirm
my understanding and augment the javadoc for others;

<h3>Paginated Mode</h3>
<p>
By configuring an instance of SelectQuery with a "page size", the List returned by performing
the query will result in <i>hollow</i> DataObjects.  Hollow in that they, in essence,
carry only their
primary key data.  Because of this, their memory foot-print should be less than if the whole
DataObject were present or "faulted".  If a DataObject is queried on a particular page in
the
list then all of the DataObject-s which are on the same page will also be faulted at the same
time.  This approach can lead to more efficient approaches to working with larger data sets.
</p>

cheers.
