All Implemented Interfaces:

Closeable, Serializable, AutoCloseable, Expressible, MapSerializable, MapWriter, NavigableObject

public class InnerJoinStream
extends BiJoinStream
implements Expressible

Joins leftStream with rightStream based on a Equalitor. Both streams must be sorted by the fields being joined on. Resulting stream is sorted by the equalitor.
