Uses commons logging Code Guards
--------------------------------
Key: NUTCH-309
URL: http://issues.apache.org/jira/browse/NUTCH-309
Project: Nutch
Type: Improvement
Versions: 0.8-dev
Reporter: Jerome Charron
Assigned to: Jerome Charron
Priority: Minor
Fix For: 0.8-dev
"Code guards are typically used to guard code that only needs to execute in
support of logging, that otherwise introduces undesirable runtime overhead in
the general case (logging disabled). Examples are multiple parameters, or
expressions (e.g. string + " more") for parameters. Use the guard methods of
the form log.is<Priority>() to verify that logging should be performed, before
incurring the overhead of the logging method call. Yes, the logging methods
will perform the same check, but only after resolving parameters."
