[slf4j-user] Expressions on log statements to avoid log guading

[Dario Garcia]

Hi everyone,

Does anyone knows if it's possible to use expressions on log variables to
avoid log guarding for costly operations?

For example, asuming that "receivedObject.getCurrentState()" is a costly
operation, what I'm doing now in my code is something like this:


if(LOG.isDebugEnabled()){
   LOG.debug("The received object has invalid state: {}",
receivedObject.getCurrentState() );
}


So I can avoid the cost of that operation when debug isn't enabled.
I would like to have some kind of expressions to avoid the extra IF:


LOG.debug("The received object has invalid state: {1.currentState}",
receivedObject)


I've seen on previous mail from Chris Pratt that someone suggested the
format from anodyzed, but I couldn't find documentation whether this was
implemented or not :

"...I would love to merge the formatter from
http://code.google.com/p/anodyzed directly into a pluggable SLF4j..."

Is this implemented or is it going to be implemented? Are there any
alternatives to what I'm doing?

Thanks in advance for your responses
