DeepCopy helps you create deep copies (clones) of your objects. It is designed to handle cycles in the association graph. How do you create deep copies of your objects (i.e. copying also all the objects referenced in the properties)? You use __clone() and implement the behavior yourself. DeepCopy recursively traverses all the object's properties and clones them. To avoid cloning the same object twice it keeps a hash map of all instances and thus preserves the object graph.
Autofetch automates adding association prefetches to object queries. Prefetch is an optimization to reduce the number of round-trips to an object store. Autofetch is designed to integrate with different object persistence technologies such as Hibernate.
