The ObjectPool class template provides parts of the functionality of the global PluginManager object pool but is intented to be used with smaller set objects, typically with same base type (e.g. factories) only. The ObjectPool takes ownership of add items if and only if the item does not have a QObject parent. Items owned by the Object pool are destructed when the pool is destructed, the other items are taken care of by their QObject parent according to the usual parent/child behavior.
