The PersistenceManager class is a basic persistence manager that is backed by a local shared object named FxAppCache. When initialized, it loads a local shared object that matches its id. If a local shared object is not found, it is created.

When storing values using the manager, it is important that all values can be properly be written to a shared object. Complex objects that store classes or non-standard flash primitives must implement flash.net.IExternalizable interface to work properly. Saving incompatible objects does not cause an RTE, but creates undefined behavior when the data is read back.
