com.google.enterprise.connector.util.diffing.DocumentSnapshot
Interface for a local copy of a document that is stored on the GSA. This represents both objects in the repository as well as serialized entries in the snapshot files (the implementations need not be the same concrete, although doing so is often convenient).
The diffing package depends on the ordering of snapshots, which must match the order of their appearance in the {@link SnapshotRepository}. By default the ordering of snapshots is determined by the lexicographic ordering of their document IDs (the natural order of Java {@code String} values).
Since version 3.0.6, the {@code DocumentSnapshot} implementationclass can also implement {@link Comparable}. The diffing package will check for the {@code Comparable} implementation beforecomparing the document IDs. Reasons to implement {@code Comparable}to define the details of the ordering include the lexicographic ordering of the document IDs, and the encoding required to make the document IDs safe to use in URLs, which might not be an order-preserving encoding (e.g., Base64 is not order-preserving). @since 2.8

    LOG.log(Level.FINE, "Building document snapshots for {0} rows.",
        rows.size());
    List<DocumentSnapshot> docList = Lists.newArrayList();
    for (Map<String, Object> row : rows) {
      try {
        DocumentSnapshot snapshot = docBuilder.getDocumentSnapshot(row);
        if (snapshot != null) {
          if (LOG.isLoggable(Level.FINER)) {
            LOG.finer("DBSnapshotRepository returns document with docID "
                + snapshot.getDocumentId());
          }
          docList.add(snapshot);
        }
      } catch (DBException e) {
        // See the similar log message in DBSnapshot.getDocumentHandle.
