class | ReturnValue |
A PersistentBase which allows copy and assignment.
Copy, assignment and destructor behavior is controlled by the traits class M.
Note: Persistent class hierarchy is subject to future changes.

A Persistent with no storage cell.

Construct a Persistent from a Local. When the Local is non-empty, a new storage cell is created pointing to the same object, and no flags are set.

The copy constructors and assignment operator create a Persistent exactly as the Persistent constructor, but the Copy function from the traits class is called, allowing the setting of flags based on the copied Persistent.

The destructor will dispose the Persistent based on the kResetInDestructor flags in the traits class. Since not calling dispose can result in a memory leak, it is recommended to always set this flag.

Persistent is a way to create a strong pointer from an off-heap object to another on-heap object. As long as the Persistent handle is alive the GC will keep the object pointed to alive. The Persistent handle is always a GC root from the point of view of the GC. Persistent must be constructed and destructed in the same thread.
