        public static int countArgs​(java.lang.String descriptor)

      • countArgs

        protected static int countArgs​(java.lang.String descriptor,
                               int widthOfLongsAndDoubles)
        Count the number of arguments in the descriptor. Each long or double counts as widthOfLongsAndDoubles; all other arguments count as 1.
        Parameters:
        descriptor - String for which arguments are counted
        widthOfLongsAndDoubles - int increment to apply for longs doubles. This is typically 1 when counting arguments alone, or 2 when counting arguments for invokeinterface.
        Returns:
        integer count
