Re: [configuration] File locator

[Oliver Heger]

If we have Loccators,  IMO there is no need to keep the base path and 
file name stuff in file based configurations. These are things a 
concrete Locator has to deal with, and the information needed by a 
Locator may vary. So I suggest the following simple method signature:

   URL locate();  // eventuelly throws ConfigurationException?
Concrete Locators should have getter and setter methods for the 
properties they need, e.g. the ClasspathLocator a resource name, the 
URLLocator a URL etc. That way a Locator could be created by Digester 
and initialized with a SetPropertiesRule, which comes in handy when used 
with ConfigurationFactory.

Usage of a Locator would then look like:
Locator locator = new MyConcreteLocator();
// init locator as necessary
Configuration conf = new PropertiesConfiguration(locator);
in contrast to
Locator locator = new MyConcreteLocator();
Configuration conf = new PropertiesConfiguration();
conf.setBasePath(...);
conf.setFileName(...);
conf.load(locator);
