question: gets the value of the extendedmetaclass 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 extendedmetaclass property . for example , to add a new item , do as follows : getextendedmetaclass . add newitem ; objects of the following type s are allowed in the list metaclasstype concode_field_sep List<MetaclassType> extendedMetaclass concode_elem_sep String metamodelUri concode_elem_sep String description concode_elem_sep String namespaceUri concode_elem_sep List<String> modelType concode_elem_sep String namespacePrefix concode_elem_sep BigInteger version concode_field_sep BigInteger getVersion concode_elem_sep String getMetamodelUri concode_elem_sep void setMetamodelUri concode_elem_sep void setNamespacePrefix concode_elem_sep String getNamespacePrefix concode_elem_sep void setNamespaceUri concode_elem_sep void setVersion concode_elem_sep List<String> getModelType concode_elem_sep String getNamespaceUri concode_elem_sep void setDescription concode_elem_sep String getDescription
target: List < MetaclassType > function ( ) { if ( extendedMetaclass == null ) { extendedMetaclass = new ArrayList < MetaclassType > ( ) ; } return this . extendedMetaclass ; }
