TObjectList is a TList descendent which has as the default array property TObjects instead of pointers. By default it also manages the objects: when an object is deleted or removed from the list, it is automatically freed. This behaviour can be disabled when the list is created.
In difference with TFPObjectList, TObjectList offers a notification mechanism of list change operations: insert, delete. This slows down bulk operations, so if the notifications are not needed, TFPObjectList may be more appropriate.
