public void	logFormatted(int level, java.lang.String message, java.lang.Object obj1) Logs a formated message. The message itself may contain % characters as place holders. This routine will attempt to match the placeholder by looking at the type of parameter passed to obj1. If the parameter is an array, it traverses the array first and matches parameters sequentially against the array items. Otherwise the parameters after message are matched in order. If the place holder matches against a number it is printed as a whole number. This can be overridden by specifying a precision in the form %n.m where n is the padding for the whole part and m is the number of decimal places to display. n can be excluded if desired. n and m may not be more than 9. If the last parameter (after flattening) is a Throwable it is logged specially. param level One of DEBUG, INFO, WARN, ERROR, FATAL param message The message to log. param obj1 The first object to match against. //do nothing
