php - Propel "ModelCriteria::FORMAT_ON_DEMAND" reuses same object? -

-

apparently using modelcriteria::format_on_demand (propelondemandformatter) not make propel hydrate objects row row , without instance pooling as documented, hydration takes place on the same object.

this means $object in example below stay same, , contents change.

$objects = objectquery::create()     ->setformatter(modelcriteria::format_on_demand)     ->find();  foreach ($objects $object) { }

this becomes problem if propel object has additional data not mapped database table columns managed in object.

why design chosen over, say, cleanly instantiating object , hydrating it? , recommended way of working design decision?

my guess better performance because no instantiation necessary.

if code expected use on-demand fetching, should override posthydrate() class of object being fetched perform necessary object-related updates data propel not automatically map columns.

note ensureconsistency() called on "rehydration" apparently not case here.

also, not store object references. refer same object record fetched last.
