  - ### Method Detail

    - #### map

          T map(Object result)

      Based on raw data set returns mapped/transformed data. Usually it will get set of raw data and return list (or collection in general) of custom object like ProcessInstance or UserTaskInstance
      Parameters:
        `result` - raw data set in custom format
      Returns:
        mapped result of raw data set

    - #### getName

          String getName()

      Returns unique name of this query result mapper implementation
      Returns:

    - #### getType

          Class<?> getType()

      Returns type of the data produced by this mapper. If the type is collection then the returned type should be type of the elements in collection e.g.:
      `List<ProcessInstanceDesc> returned type should be ProcessInstanceDesc.class`
      Returns:

    - #### forColumnMapping

          QueryResultMapper<T> forColumnMapping(Map<String,String> columnMapping)

      Returns new instance of the mapper for given column mapping
      Parameters:
        `columnMapping` - provides column mapping (name to type) that can be shipped to mapper for improved transformation - can be null (accepted types: string, long, integer, date, double)
      Returns:
        new instance of the mapper configured with column mapping
