question: gets the value of the viburls 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 viburls property . for example , to add a new item , do as follows : getviburls . add newitem ; objects of the following type s are allowed in the list string concode_field_sep List<String> bundleUrls concode_elem_sep List<String> vibUrls concode_elem_sep ManagedObjectReference _this concode_elem_sep HostPatchManagerPatchManagerOperationSpec spec concode_elem_sep List<String> metaUrls concode_field_sep void setThis concode_elem_sep ManagedObjectReference getThis concode_elem_sep List<String> getBundleUrls concode_elem_sep HostPatchManagerPatchManagerOperationSpec getSpec concode_elem_sep void setSpec concode_elem_sep List<String> getMetaUrls
target: List < String > function ( ) { if ( vibUrls == null ) { vibUrls = new ArrayList < String > ( ) ; } return this . vibUrls ; }
