gets the value of the forwardcompatibilitymap 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 forwardcompatibilitymap property . for example , to add a new item , do as follows : getforwardcompatibilitymap . add newitem ; objects of the following type s are allowed in the list stringstringmapentry concode_field_sep AdGroupAdApprovalStatus approvalStatus concode_elem_sep List<String> disapprovalReasons concode_elem_sep Ad ad concode_elem_sep AdGroupAdExperimentData experimentData concode_elem_sep Boolean trademarkDisapproved concode_elem_sep Long adGroupId concode_elem_sep List<StringStringMapEntry> forwardCompatibilityMap concode_elem_sep AdGroupAdStatus status concode_elem_sep List<Label> labels concode_field_sep void setAd concode_elem_sep Ad getAd concode_elem_sep void setTrademarkDisapproved concode_elem_sep Long getAdGroupId concode_elem_sep AdGroupAdApprovalStatus getApprovalStatus concode_elem_sep void setExperimentData concode_elem_sep AdGroupAdStatus getStatus concode_elem_sep void setStatus concode_elem_sep void setAdGroupId concode_elem_sep List<String> getDisapprovalReasons concode_elem_sep List<Label> getLabels concode_elem_sep AdGroupAdExperimentData getExperimentData concode_elem_sep void setApprovalStatus concode_elem_sep Boolean isTrademarkDisapproved
