Package org.apache.solr.client.solrj.io.stream

Class BiJoinStream

java.lang.Object

org.apache.solr.client.solrj.io.stream.TupleStream

org.apache.solr.client.solrj.io.stream.JoinStream

org.apache.solr.client.solrj.io.stream.BiJoinStream

All Implemented Interfaces:

Closeable, Serializable, AutoCloseable, Expressible, org.apache.solr.common.MapSerializable, org.apache.solr.common.MapWriter, org.apache.solr.common.NavigableObject, org.noggit.JSONWriter.Writable

Direct Known Subclasses:

InnerJoinStream, LeftOuterJoinStream

public abstract class BiJoinStream
extends JoinStream
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.
