[slf4j-dev] Logger.debug(String, Object[])?

[Curt Arnold]

Been reading the varargs stuff in JDK 1.5 and it seems like it might  
be desirable to add methods that take an Object[] parameter in  
addition to the existing Logger.debug(String, Object) methods.  For  
example:

interface Logger {
void debug(String format, Object param1); //existing method
void debug(String format, Object[] params);
}

The second form would be like a

void debug(String format, Object... params)

Obviously there would be a construction cost in constructing the  
array unless you happened to happened to have it around.  However, if  
you were willing to take the hit, it would open up all sorts of  
combinations of parameters.

The implementation  would be something like:

void debug(String format, Object param1) {
    if (isDebugEnabled()) {
        String msg = MessageFormat.format(new Object[] { param1 });
        logger.finer(msg);
    }
}

void debug(String format, Object[] params) {
    if (isDebugEnabled()) {
        String msg = MessageFormat.format(params);
        logger.finer(msg);
    }
}

This way, you could do:

logger.debug("This first five letters of the latin alphabet are {},  
{}, {}, {}, {}.", new Object[] {"A", "B", "C", "D", "E" });
