code: public List<JAXBElement<? extends ActionType>> getAction() {
          if (action == null) {

docs: Gets the value of the action property.
  
  <p>
  This accessor method returns a reference to the live list,
  not a snapshot. Therefore any modification you make to the
  returned list will be present inside the JAXB object.
  This is why there is not a <CODE>set</CODE> method for the action property.
  
  <p>
  For example, to add a new item, do as follows:
  <pre>
  getAction().add(newItem);
  </pre>
  
  
  <p>
  Objects of the following type(s) are allowed in the list
  {@link JAXBElement }{@code <}{@link AlertAction }{@code >}
  {@link JAXBElement }{@code <}{@link ActionType }{@code >}
  {@link JAXBElement }{@code <}{@link CustomAction }{@code >}
  {@link JAXBElement }{@code <}{@link EmailAction }{@code >}
