[Gusdev-gusdev] getChildren and objects with the same id

[Jonathan S. <js...@pc...>]

Gregory:

I'm looking into this problem.  It may be due to the violation you  
suggest.

Perhaps a better work-around/solution is to maintain a cache of  
objects, e.g., { na_sequence_id => GUS::Model::DoTS::NASequence }.   
Then as you scan through your list of Similarities you can easily see  
if you have already processed that na_sequence_id already and readily  
get your hands on the object if you really want to reprocess it.  Of  
course this is solution may require more memory, but it sounds as  
though you already have multiple objects in memory at one time.

Note to GUS developers:  I seem to remember that we have discussed this  
idea before, but let me float it again.  Should we consider changing  
retrieveFromDB or adding another, similar, routine that actually  
returns a pointer to the (cached) object?  If the object can not be  
retrieved from the DB then it returns undef.  If the object is already  
loaded, it returns that object.  If the object is novel, then it  
returns the caller's notion of the object.  Here are a couple of ways  
to use such a method.

my $_obj = GUS::Model::Schema::Table->new({ table_id => 123 });
$_obj = _$obj->uniquelyRetrieveFromDb();
if (!_obj) {
	die "Could not find object 123 in db.";
}

OR

my $_obj = GUS::Model::Schema::Table
	->new({ table_id => 123 })
	->uniquelyRetrieveFromDb();

if (!$_obj) {
	die "Could not find object 123 in db.";
}

Thoughts?
