      • onAllChildrenAddedToPage

        public static void onAllChildrenAddedToPage​(DomElement element,
                                            boolean postponed)
        Lifecycle method invoked after a node and all its children have been added to a page, during parsing of the HTML. Intended to be overridden by nodes which need to perform custom logic after they and all their child nodes have been processed by the HTML parser. This method is not recursive, and the default implementation is empty, so there is no need to call super.onAllChildrenAddedToPage() if you implement this method.
        Parameters:
        element - the element
        postponed - whether to use PostponedAction or no
