+/**
+ * PersistentObject base class that implements getter/setter methods for all mapped fields and associations
+ * by overriding __call.
+ *
+ * This class is a forward compatible implementation of the PersistentObject trait.
+ *
+ * Limitations:
+ *
+ * 1. All persistent objects have to be associated with a single ObjectManager, multiple
+ *    ObjectManagers are not supported. You can set the ObjectManager with `PersistentObject#setObjectManager()`.
+ * 2. Setters and getters only work if a ClassMetadata instance was injected into the PersistentObject.
+ *    This is either done on `postLoad` of an object or by accessing the global object manager.
+ * 3. There are no hooks for setters/getters. Just implement the method yourself instead of relying on __call().
+ * 4. Slower than handcoded implementations: An average of 7 method calls per access to a field and 11 for an association.
+ * 5. Only the inverse side associations get autoset on the owning side as well. Setting objects on the owning side
+ *    will not set the inverse side associations.
+ *
+ * @deprecated Deprecated `PersistentObject` class in 1.2. Please implement this functionality
+ *             directly in your application if you want ActiveRecord style functionality.
+ *
+ * @example
+ *
+ *  PersistentObject::setObjectManager($em);
+ *
+ *  class Foo extends PersistentObject
+ *  {
+ *      private $id;
+ *  }
+ *
+ *  $foo = new Foo();
+ *  $foo->getId(); // method exists through __call
