Class RidSet

java.lang.Object

com.arcadedb.query.sql.executor.RidSet

All Implemented Interfaces:

Iterable<RID>, Collection<RID>, Set<RID>

public class RidSet
extends Object
implements Set<RID>

Special implementation of Java Set<ORID> to efficiently handle memory and performance. It does not store actual RIDs, but it only keeps track that a RID was stored, so the iterator will return new instances.
