== LogFactory as factory for Log instances
Currently, JCL uses a LogFactory to create Log instances:
Log log = LogFactory.getLog("fff");
By contrast, Log4j has the factory method on the Log class:
Logger log = Logger.getLog("fff");
Having one less class is a *little* nicer for users I think. However it
does reduce the flexibility of the system a little and changing this is
a major difference from JCL 1.x.
My choice would be: keep LogFactory and LogFactory.getLog as the
mechanism for obtaining Log instances.
There is one really big advantage of the current API in this case:
If you want to have Logger.getLog("fff") Logger must be a class,
currently it is an interface.
Please do not switch from an interface to an class, since it is
impossible to provide a native
implementation of JCL2 without an interface.
It's possible to keep a Log interface and having one less class to
import by adding a static class in the Log interface. It would look like
this:
Log log = Log.Factory.getLog("foo");
I don't expect everyone to like it ;) I personally prefer the
Log4j/JDK1.4 syntax.
