ManagedBacking class Null safety

Instances of this class provide storage for ManagedObjects.

This class is primarily used internally.

A ManagedObject stores properties declared by its type argument in instances of this type. Values are validated against the ManagedObject.entity.

Instances of this type only store properties for which a value has been explicitly set. This allows serialization classes to omit unset values from the serialized values. Therefore, instances of this class provide behavior that can differentiate between a property being the null value and a property simply not being set. (Therefore, you must use removeProperty instead of setting a value to null to really remove it from instances of this type.)

Conduit implements concrete subclasses of this class to provide behavior for property storage and query-building.
