    • instantiateExplainStep

      public QueryRecord.PartialResult.ExplainStep instantiateExplainStep(Filter filter)
      Instantiate a new explain step for the given filter and add it to this result's list of steps. This method is called on the server for the top level filter.
      Parameters:
      filter - the filter
      Returns:
      the new explain step

    • instantiateTraceStep

      public QueryRecord.PartialResult.TraceStep instantiateTraceStep(Filter filter)
      Instantiate a new trace step for the given filter and add it to this result's list of steps. This method is called on the server for the top level filter(s).
      Parameters:
      filter - the filter
      Returns:
      the new trace step

    • merge

      protected void merge(QueryRecord.PartialResult result)
      Merge the given result with this one.
      Parameters:
      result - the result to merge

    • isMatching

      protected boolean isMatching(QueryRecord.PartialResult result)
      Determine whether or not the given result is capable of being placed in one-to-one correspondence with this result. Results are matching if their owned lists of steps have the same size, and all pairs of steps in the two lists are matching.
      Parameters:
      result - the result to be checked
      Returns:
      true iff the given result matches with this result
