Each line can be: // // (a) a blank line // // (b) a comment, which is a line that begins with "//" // // (c) one of three possible use counter declarations: // // method . // attribute . // property // // The |CSS property method name| should be identical to the |method| // argument to CSS_PROP and related macros. The method name is // identical to the name of the property, except that all hyphens are // removed and CamelCase naming is used. See nsCSSPropList.h for // further details. // // To actually cause use counters to be incremented, DOM methods // and attributes must have a [UseCounter] extended attribute in // the Web IDL file. CSS properties require no special treatment // beyond being listed below. // // You might reasonably ask why we have this file and we require // annotating things with [UseCounter] in the relevant WebIDL file as // well. Generating things from bindings codegen and ensuring all the // dependencies were correct would have been rather difficult, and // annotating the WebIDL files does nothing for identifying CSS // property usage, which we would also like to track. method SVGSVGElement.getElementById attribute SVGSVGElement.currentScale property Fill property FillOpacity // Push API method PushManager.subscribe method PushSubscription.unsubscribe // window.sidebar.addSearchEngine attribute Window.sidebar method External.addSearchEngine // AppCache API method OfflineResourceList.swapCache method OfflineResourceList.update attribute OfflineResourceList.status attribute OfflineResourceList.onchecking attribute OfflineResourceList.onerror attribute OfflineResourceList.onnoupdate attribute OfflineResourceList.ondownloading attribute OfflineResourceList.onprogress attribute OfflineResourceList.onupdateready attribute OfflineResourceList.oncached attribute OfflineResourceList.onobsolete
