All Implemented Interfaces:

public class MemoryNullIndexer
extends NullIndexer

Defines a trivial indexer that projects the contents of a memory-equipped node to the empty tuple, and can therefore save space. Can only exist in connection with a memory, and must be operated by another node. Do not attach parents directly!
