        public String getLinkId()
        An identifier that is unique within the Questionnaire allowing linkage to the equivalent item in a QuestionnaireResponse resource.
        Returns:
        An immutable object of type String that is non-null.

      • getDefinition

        public Uri getDefinition()
        This element is a URI that refers to an [ElementDefinition](elementdefinition.html) that provides information about this item, including information that might otherwise be included in the instance of the Questionnaire resource. A detailed description of the construction of the URI is shown in Comments, below. If this element is present then the following element values MAY be derived from the Element Definition if the corresponding elements of this Questionnaire resource instance have no value:

        * code (ElementDefinition.code)

        * type (ElementDefinition.type)

        * required (ElementDefinition.min)

        * repeats (ElementDefinition.max)

        * maxLength (ElementDefinition.maxLength)

        * answerValueSet (ElementDefinition.binding)

        * options (ElementDefinition.binding).

        Returns:
        An immutable object of type Uri that may be null.

        A constraint indicating that this item should only be enabled (displayed/allow answers to be captured) when the specified condition is true.
        Returns:
        An unmodifiable list containing immutable objects of type Questionnaire.Item.EnableWhen that may be empty.

      • getEnableBehavior

        public void accept​(java.lang.String elementName,
                   int elementIndex,
                   Visitor visitor)
        Description copied from interface: Visitable
        Accept a Visitor and invoke the appropriate visit methods. A typical implementation would look like this: 
         if (visitor.preVisit(this)) {
     visitor.visitStart(elementName, elementIndex, this);
     if (visitor.visit(elementName, elementIndex, this)) {
         // visit children
     }
     visitor.visitEnd(elementName, elementIndex, this);
     visitor.postVisit(this);
 }
        Specified by:
        accept in interface Visitable
        Specified by:
        accept in class AbstractVisitable
        Parameters:
        elementName - the name of the element in the context of this visit
        elementIndex - the index of the element in a list or -1 if it is not contained within a List
        visitor - the visitor to use
