Package com.orientechnologies.orient.core.id

Interface ORID

All Superinterfaces:

Comparable<OIdentifiable>, Comparator<OIdentifiable>, OIdentifiable, OSerializableStream, Serializable

All Known Implementing Classes:

OContextualRecordId, OImmutableRecordId, ORecordId

public interface ORID
extends OIdentifiable, OSerializableStream

RecordID interface that represents a recordid in database. RecordID are made of 2 numbers: cluster id (cluster number) and cluster position (absolute position inside the cluster). Loading a record by its RecordID allows O(1) performance, no matter the database size.
