Class MemoryIdentityIndexer

java.lang.Object

org.eclipse.viatra.query.runtime.rete.network.BaseNode

org.eclipse.viatra.query.runtime.rete.index.StandardIndexer

org.eclipse.viatra.query.runtime.rete.index.SpecializedProjectionIndexer

org.eclipse.viatra.query.runtime.rete.index.MemoryIdentityIndexer

All Implemented Interfaces:

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

public class MemoryIdentityIndexer
extends IdentityIndexer

Defines a trivial indexer that identically projects the contents of a memory-equipped node, 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!
