Class MemoryNullIndexer

java.lang.Object

org.eclipse.incquery.runtime.rete.network.BaseNode

org.eclipse.incquery.runtime.rete.index.StandardIndexer

org.eclipse.incquery.runtime.rete.index.SpecializedProjectionIndexer

org.eclipse.incquery.runtime.rete.index.NullIndexer

org.eclipse.incquery.runtime.rete.index.MemoryNullIndexer

All Implemented Interfaces:

java.lang.Iterable<Tuple>, Indexer, IterableIndexer, ProjectionIndexer, Node

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!

Parameters:

reteContainer -

tupleWidth - the width of the tuples of memoryNode

memory - the memory whose contents are to be null-indexed

parent - the parent node that owns the memory
