[slf4j-dev] svn commit: r1155 - in slf4j/trunk/slf4j-ext/src/main/java/org/slf4j: agent instrumentation

[Ralph Goers]

Thanks,

I'm quite interested in this, but not only for entering and exiting but 
eventually for other logging as well.  However,  I wouldn't want it in 
all classes. I'd prefer to see additional configuration to define which 
classes should be instrumented.

Also, once the logging is injected would it be able to be removed?

In other words, eventually I'd like to see enabling and disabling of 
logging (i.e. the equivalent of configuring Loggers) done via AOP.
