  public DummyIndex()

Method Detail

• getSchema

  public Schema<ChangeData> getSchema()

  Specified by:

  getSchema in interface ChangeIndex

  Returns:

  the schema version used by this index.

• close

  public void close()

  Description copied from interface: ChangeIndex
  Close this index.

  Specified by:

  close in interface ChangeIndex

• insert

  public void insert(ChangeData cd)
              throws java.io.IOException

  Description copied from interface: ChangeIndex
  Insert a change document into the index.

  Results may not be immediately visible to searchers, but should be visible within a reasonable amount of time.

  Specified by:

  insert in interface ChangeIndex

  Parameters:

  cd - change document

  Throws:

  java.io.IOException - if the change could not be inserted.

• replace

  public void replace(ChangeData cd)
               throws java.io.IOException

  Description copied from interface: ChangeIndex
  Update a change document in the index.

  Semantically equivalent to deleting the document and reinserting it with new field values. Results may not be immediately visible to searchers, but should be visible within a reasonable amount of time.

  Specified by:

  replace in interface ChangeIndex

  Parameters:

  cd - change document

  Throws:

  java.io.IOException

• delete

  public void delete(ChangeData cd)
              throws java.io.IOException

  Description copied from interface: ChangeIndex
  Delete a change document from the index.

  Specified by:

  delete in interface ChangeIndex

  Parameters:

  cd - change document

  Throws:

  java.io.IOException

• deleteAll

  public void deleteAll()
                 throws java.io.IOException

  Description copied from interface: ChangeIndex
  Delete all change documents from the index.

  Specified by:

  deleteAll in interface ChangeIndex

  Throws:

  java.io.IOException

• getSource

  public ChangeDataSource getSource(Predicate<ChangeData> p,
                           int start,
                           int limit)
                             throws com.google.gerrit.server.query.QueryParseException

  Description copied from interface: ChangeIndex
  Convert the given operator predicate into a source searching the index and returning only the documents matching that predicate.

  This method may be called multiple times for variations on the same predicate or multiple predicate subtrees in the course of processing a single query, so it should not have any side effects (e.g. starting a search in the background).

  Specified by:

  getSource in interface ChangeIndex

  Parameters:

  p - the predicate to match. Must be a tree containing only AND, OR, or NOT predicates as internal nodes, and IndexPredicates as leaves.

  start - offset in results list at which to start returning results.

  limit - maximum number of results to return.

  Returns:

  a source of documents matching the predicate. Documents must be returned in descending sort key order, unless a sortkey_after predicate (with a cut point not at Long.MAX_VALUE) is provided, in which case the source should return documents in ascending sort key order starting from the sort key cut point.

  Throws:

  com.google.gerrit.server.query.QueryParseException - if the predicate could not be converted to an indexed data source.

• markReady

  public void markReady(boolean ready)
                 throws java.io.IOException

  Description copied from interface: ChangeIndex
  Mark whether this index is up-to-date and ready to serve reads.

  Specified by:

  markReady in interface ChangeIndex

  Parameters:

  ready - whether the index is ready

  Throws:

  java.io.IOException

• delete

  public void delete(int id)
              throws java.io.IOException

  Description copied from interface: ChangeIndex
  Delete a change document from the index by id.

  Specified by:

  delete in interface ChangeIndex

  Parameters:

  id - change document id

  Throws:

  java.io.IOException
