  +--org.apache.poi.util.POILogger
public class POILogger
extends java.lang.Object

A logger class that strives to make it as easy as possible for developers to write log calls, while simultaneously making those calls as cheap as possible by performing lazy evaluation of the log message.

logFormatted

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.

Parameters:
level - One of DEBUG, INFO, WARN, ERROR, FATAL
message - The message to log.
obj1 - The first object to match against.
