I would like to retrieve all instances of a particular object type (e.g., com.arsdigita.kernel.User). How do I do this?
There is a method on com.arsdigita.persistence.Session (http://rhea.redhat.com/doc/waf/6.0/api/com/arsdigita/persistence/Session.html) that retrieves a DataCollection for all instances of a data object type. The DataCollection can be filtered to narrow the results. It is possible to request individual properties of the collection without instantiating an object. You can also instantiate the data object, and if you use the DomainObjectFactory, you can get a DomainObject from the data object. It is recommended, however, that you do not instantiate the object unless absolutely necessary, because creating the object consumes extra memory resources as compared to iterating through the DomainCollection.
