http://issues.apache.org/bugzilla/show_bug.cgi?id=38953 Summary: Need addition of clone() method/concept to Configuration interface and/or implementing classes Product: Commons Version: 1.2 Final Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: Configuration AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] Original email text: --- >The HierarchicalConfiguration class contains a clone() method, to allow >decoupling of a configuration from the underlying file to prevent ill >effects during configuration updates. So, for example, I can clone an >XMLConfiguration for a user's session in a web app and update the >configuration file underneath so that the updates will be active for the >next user and the current user will not experience some undesirable >effect due to the change. > >My question is why this concept does not exist at a higher level? It >would seem that any class that implements the FileConfiguration >interface (and therefore the ReloadingStategy concept), should implement >a method that allows the configuration to be temporarily decoupled from >the source. Are there any plans for cloning to be enforced at a >FileConfiguration level? > >>From a completely selfish standpoint, I have a CompositeConfiguration >object that contains several PropertiesConfigurations and >XMLConfigurations with different reloading strategies. I'd like to >clone this for each user session for the above mentioned reason. >Ideally, the CompositeConfiguration would be clonable (cloning each of >the encapsulated configurations), but barring that, it would be nice to >be able to loop through the contained configurations and perform a >FileConfiguration.clone() on each object.

Would you be so kind to open an enhancement ticket for this in bugzilla, so this idea won't get lost (see http://jakarta.apache.org/commons/configuration/issue-tracking.html)? Thanks. What may help you ATM are some utility methods in ConfigurationUtils for copying configurations. You might have a look at this class and maybe you can use some of the stuff to solve your problem.
