java.lang.Object org.apache.any23.filter.IgnoreTitlesOfEmptyDocuments
public class IgnoreTitlesOfEmptyDocuments
A TripleHandler
that suppresses output of the
TitleExtractor
unless some other triples could
be parsed from the document. This is used when we don't
want to have single-triple RDF documents around that
contain only the title triple.
