gets the value of the mapper 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 mapper property . for example , to add a new item , do as follows : getmapper . add newitem ; objects of the following type s are allowed in the list mapper concode_field_sep Result result concode_elem_sep List<Mapper> mapper concode_elem_sep XMLGregorianCalendar finished concode_elem_sep long serialVersionUID concode_elem_sep Type type concode_elem_sep List<Sync> sync concode_elem_sep XMLGregorianCalendar begin concode_elem_sep Exceptions exceptions concode_field_sep XMLGregorianCalendar getBegin concode_elem_sep boolean isSetResult concode_elem_sep void setResult concode_elem_sep void unsetMapper concode_elem_sep boolean isSetBegin concode_elem_sep void setBegin concode_elem_sep void setExceptions concode_elem_sep boolean isSetMapper concode_elem_sep void setType concode_elem_sep boolean isSetType concode_elem_sep Exceptions getExceptions concode_elem_sep boolean isSetSync concode_elem_sep boolean isSetExceptions concode_elem_sep List<Sync> getSync concode_elem_sep Type getType concode_elem_sep boolean isSetFinished concode_elem_sep Result getResult concode_elem_sep XMLGregorianCalendar getFinished concode_elem_sep void unsetSync concode_elem_sep void setFinished
