## Interface ResultWriter

- All Known Implementing Classes:
    QuerySources.BatchWriter

      @NotThreadSafe
      public interface ResultWriter

  A writer passed by ModeShape to a `Index.Operation` instance when the query engine needs additional results for the query.

  Instances of this type are created by ModeShape and passed into the `Index.Operation.getNextBatch(ResultWriter, int)` method. Thus, providers do not need to implement this interface (except maybe for testing purposes).
