createNodeValidator

NodeValidator<? extends L> createNodeValidator(K key)

Create a node validator that knows how to validate nodes for items that are specified by the given key. The key can be almost anything. The interpretation of it is entirely up to the factory implementation.

Parameters:

key - A key that can be used to identify which items the node validator should handle

Returns:

A node validator object, or null if no validator exists

Throws:

ItemNotFoundException - If a node loader for the given key can't be found. NOTE! Instead of throwing an exception it is possible to simply return null or a NullNodeValidator or any other "generic" implementation.

BaseException - If there is any other problem creating the node validator
