java.lang.Object
  org.galagosearch.core.index.DocumentLengthsWriter

All Implemented Interfaces:

org.galagosearch.tupleflow.Processor<org.galagosearch.core.types.NumberedDocumentData>, org.galagosearch.tupleflow.Step

@InputClass(className="org.galagosearch.core.types.NumberedDocumentData",
            order="+number")
public class DocumentLengthsWriter
extends java.lang.Object
implements org.galagosearch.tupleflow.Processor<org.galagosearch.core.types.NumberedDocumentData>

Writes the document lengths file based on data in NumberedDocumentData tuples. The document lengths data is used by StructuredIndex because it's a key input to more scoring functions.
