warn

public void warn(String format,
                 Object... arguments)

Description copied from interface: Logger

Log a message at the WARN level according to the specified format and arguments.

This form avoids superfluous string concatenation when the logger is disabled for the WARN level. However, this variant incurs the hidden (and relatively small) cost of creating an Object[] before invoking the method, even if this logger is disabled for WARN. The variants taking one and two arguments exist solely in order to avoid this hidden cost.

Specified by:

warn in interface Logger

Parameters:

format - the format string

arguments - a list of 3 or more arguments
