Class UpdateExtWorkDelegate

java.lang.Object
  org.hibernate.search.backend.impl.lucene.works.UpdateWorkDelegate
      org.hibernate.search.backend.impl.lucene.works.UpdateExtWorkDelegate

All Implemented Interfaces:

LuceneWorkDelegate

public final class UpdateExtWorkDelegate
extends UpdateWorkDelegate

This applies the index update operation using the Lucene operation IndexWriter.updateDocument(Term, org.apache.lucene.document.Document, org.apache.lucene.analysis.Analyzer) This is the most efficient way to update the index, but we can apply it only if the Document is uniquely identified by a single term (so no index sharing across entities or Numeric ids).
