Is there a need to do a if(log.isDebugEnabled()) { ... } check?

is there a need to do an explicit if(log.isDebugEnabled()) { ... } check?

I mean i have seen some post mentioning that log.debug("something") does an implicit call to see if debug mode logging has been enabled, before it does the logging. Am i missing something or is there an intermediary step that is to be performed before this is used?

Thanks!

log.debug("ResultSet rs is retrieved from OracleTypes");

if(log.isDebugEnabled()){
     log.debug("ResultSet rs is retrieved from OracleTypes");
}
