java.lang.Object
  org.galagosearch.tupleflow.StandardStep<Document,Document>
      org.galagosearch.core.parse.DateExtractor

All Implemented Interfaces:

org.galagosearch.tupleflow.Processor<Document>, org.galagosearch.tupleflow.Source<Document>, org.galagosearch.tupleflow.Step

@InputClass(className="org.galagosearch.core.parse.Document")
@OutputClass(className="org.galagosearch.core.types.DateExtent")
public class DateExtractor
extends org.galagosearch.tupleflow.StandardStep<Document,Document>

A very crude extractor of dates from text. This class searches for anything that looks like a year (1000-2999), then searches around that year for a month name. A year is sufficient to emit a date. Day of the month is currently not supported.
