gets the value of the topology 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 topology property . for example , to add a new item , do as follows : gettopology . add newitem ; objects of the following type s are allowed in the list evidencedstringtype concode_field_sep List<EvidencedStringType> orientation concode_elem_sep List<EvidencedStringType> topology concode_elem_sep List<EvidencedStringType> location concode_field_sep List<EvidencedStringType> getLocation concode_elem_sep List<EvidencedStringType> getOrientation
List < EvidencedStringType > function ( ) { if ( topology == null ) { topology = new ArrayList < EvidencedStringType > ( ) ; } return this . topology ; }
