Instance Method Details

#log(*args) ⇒ Object

Writes a string to the logger. Writing of the string is skipped if the string’s log level is higher than the logger’s log level. If the logger responds to write_nonblock and is not on the java or windows platforms then the logger will use non-blocking asynchronous writes.
