    - #### GenericResponse

          public GenericResponse()

      Creates an empty BaseResponse.

    - #### GenericResponse

          public GenericResponse(List list)

      Creates a BaseResponse with a single result list.

      Creates a response that it a shallow copy of another response.

  - ### Method Detail

    - #### firstList

          public List firstList()

      Description copied from interface: `QueryResponse`
      A utility method for quickly retrieving the first list in the response. Returns null if the query has no lists. Note that this method resets current iterator to an undefined state.
      Specified by:
        `firstList` in interface `QueryResponse`

    - #### firstUpdateCount

          public int[] firstUpdateCount()

      Description copied from interface: `QueryResponse`
      A utility method for quickly retrieving the first update count from the response. Note that this method resets current iterator to an undefined state.
      Specified by:
        `firstUpdateCount` in interface `QueryResponse`

    - #### currentList

          public List currentList()

      Description copied from interface: `QueryResponse`
      Returns a List under the current iterator position. Use `QueryResponse.isList()` to check the result type before calling this method.
      Specified by:
        `currentList` in interface `QueryResponse`

    - #### currentUpdateCount

          public int[] currentUpdateCount()

      Description copied from interface: `QueryResponse`
      Returns an update count under the current iterator position. Returned value is an int[] to accommodate batch queries. For a regular update result, the value will be an int[1]. Use `QueryResponse.isList()` to check the result type before calling this method.
      Specified by:
        `currentUpdateCount` in interface `QueryResponse`

    - #### isList

          public boolean isList()

      Description copied from interface: `QueryResponse`
      Returns whether current iteration result is a list or an update count.
      Specified by:
        `isList` in interface `QueryResponse`

    - #### next

          public boolean next()

      Description copied from interface: `QueryResponse`
      Rewinds response iterator to the next result, returning true if it is available.
      Specified by:
        `next` in interface `QueryResponse`

    - #### reset

          public void reset()

      Description copied from interface: `QueryResponse`
      Restarts response iterator.
      Specified by:
        `reset` in interface `QueryResponse`

    - #### size

          public int size()

      Description copied from interface: `QueryResponse`
      Returns a number of results in the response.
      Specified by:
        `size` in interface `QueryResponse`

    - #### clear

          public void clear()

      Clears any previously collected information.

    - #### addBatchUpdateCount

          public void addBatchUpdateCount(int[] resultCount)

    - #### addUpdateCount

          public void addUpdateCount(int resultCount)

    - #### addResultList

          public void addResultList(List list)

    - #### replaceResult

          public void replaceResult(Object oldResult,
                                    Object newResult)

      Replaces previously stored result with a new result.
