NullNode Class Reference

Detailed Description

NullNode is an implementation of the NullObject pattern, It inherits all functionality from Node (acts like a Node) and is only distinguishable from a Node instance by it's class or oid.

If a Node's parent is a NullNode instance, than they should be separated in the data store (e.g. the foreign key should be null, if allowed by the database). NullNode child instances should be ignored.
