question: gets the value of the message property . 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 set method for the message property . for example , to add a new item , do as follows : getmessage . add newitem ; objects of the following type s are allowed in the list message concode_field_sep List<LocalizedMessage> localizedMessage concode_elem_sep String name concode_elem_sep List<Message> message concode_elem_sep List<ValidationContext> child concode_field_sep void setName concode_elem_sep String getName concode_elem_sep List<LocalizedMessage> getLocalizedMessage concode_elem_sep List<ValidationContext> getChild
target: List < Message > function ( ) { if ( message == null ) { message = new ArrayList < Message > ( ) ; } return this . message ; }
