- - ### Constructor Detail

    - #### ProcessInstanceQueryMapper

          public ProcessInstanceQueryMapper()

      Dedicated for ServiceLoader to create instance, use `get()` method instead

  - ### Method Detail

    - #### get

          public static ProcessInstanceQueryMapper get()

      Default access to get instance of the mapper
      Returns:

    - #### map

          public List<ProcessInstanceDesc> map(Object result)

      Description copied from interface: `QueryResultMapper`
      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
      Specified by:
        `map` in interface `QueryResultMapper<List<ProcessInstanceDesc>>`
      Parameters:
        `result` - raw data set in custom format
      Returns:
        mapped result of raw data set

    - #### buildInstance

          protected ProcessInstanceDesc buildInstance(org.dashbuilder.dataset.DataSet dataSetResult,
                                                      int index)

      Specified by:
        `buildInstance` in class `AbstractQueryMapper<ProcessInstanceDesc>`

    - #### getName

          public String getName()

      Description copied from interface: `QueryResultMapper`
      Returns unique name of this query result mapper implementation
      Specified by:
        `getName` in interface `QueryResultMapper<List<ProcessInstanceDesc>>`
      Returns:

    - #### getType

          public Class<?> getType()

      Description copied from interface: `QueryResultMapper`
      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`
      Specified by:
        `getType` in interface `QueryResultMapper<List<ProcessInstanceDesc>>`
      Returns:

    - #### forColumnMapping

          public QueryResultMapper<List<ProcessInstanceDesc>> forColumnMapping(Map<String,String> columnMapping)

      Description copied from interface: `QueryResultMapper`
      Returns new instance of the mapper for given column mapping
      Specified by:
        `forColumnMapping` in interface `QueryResultMapper<List<ProcessInstanceDesc>>`
      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
