    - #### startProcessing

          public void startProcessing()

      Description copied from interface: `MediaCriteriaProcessor`
      Informs the processor the start of the process. The processor use this method to allocate all the resources required by the processing here. It uses it to initialize the processor state machine.
      Specified by:
        `startProcessing` in interface `MediaCriteriaProcessor`

    - #### endProcessing

          public void endProcessing()

      Description copied from interface: `MediaCriteriaProcessor`
      Informs the processor the process is ended. The processor use this method to deallocate all the resources that were used during the processing. It uses it to tear down the processor state machine or to finalize some treatments.

      The processing has to stop once this method is called. Hence, the call of process methods should result to nothing or to an exception.
      Specified by:
        `endProcessing` in interface `MediaCriteriaProcessor`

    - #### result

          public org.silverpeas.core.persistence.jdbc.sql.JdbcSqlQuery result()

      Description copied from interface: `MediaCriteriaProcessor`
      Gets the result of the processing. Warning, the result can be incomplete if called before the processing ending (triggered with the call of `MediaCriteriaProcessor.endProcessing()` method).
      Specified by:
        `result` in interface `MediaCriteriaProcessor`
      Returns:
        the processing result.

    - #### then

          public MediaCriteriaProcessor then()

      Description copied from interface: `MediaCriteriaProcessor`
      Informs the processor that there is a new criterion to process. This method must be used by the caller to chain the different criterion processings.
      Specified by:
        `then` in interface `MediaCriteriaProcessor`
      Returns:
        the processor itself.
