## Interface IQuestionnaireService

-     public interface IQuestionnaireService

  Interface for the Questionnaire objects and operations.

  >      Gateway to questionnaire objects and operations.
  >      Use this service to read and update questionnaire resource ( both template and response )
  >      The program can be launched by this service as well.

      Get a questionnaire object by Id for the the current period including all sections and questions
      Parameters:
        `id` - (required) The Id of the object to retrieve. The object type has to be either QuestionnaireTemplate or QuestionnaireAssessment.
      Returns:
        IQuestionnaire questionnaire instance if it exists, otherwise null. The object returned is for the current period and includes all sections and questions

    - #### saveQuestionnaire

          IQuestionnaire saveQuestionnaire(IQuestionnaire questionnaire)

      Save a questionnaire
      Parameters:
        `questionnaire` - (required) The questionnaire to save
