I read the doc, and I only saw DataObject::get(). without the ability to restrict the Select.
With get you can have access to all the fields available for the class.
But is it possible to restrict the result, I mean something like MyClass::get(array('fied1','field2')); which generates a SELECT field1, filed2 whereas withe the get() you have SELECT *
I do not see this possibility in the Doc/Api. Is there a way to do this ?
