RE: - Setting logging levels

[Bender Heri <HB...@Ergonomics.ch>]

If the string which you supply to logger.info() must first be constructed (normally a expensive operation which you dont want to do if info is not enabled) you can avoid this by:

if ( logger.isInfoEnabled() )
{
    logger.info( prepareString( args ) );
}

Without this surrounding if the string would be constructed anyway only in order that the log frameworks throws it away if the desired level is not enabled.

The isXXXEnabled() exists for each level.
