Hi,
when working over a new module there's often a decision to be made, about
where
the configuration should be stored and how.
While custom configuration files are a popular choice, they also have
significant downsides:
* the config in question cannot be edited via REST config
* persistance has to be managed by the plugin
* the config sometimes really is something related to a particular catalog
resource, so it
would be better placed as part of the resource metadata map
Of course one can put whatever is needed in the metadata map, but the
default
XStream persistence can leave a lot to be desired, with package names
included
in the element names and the like, to the point of making the metadata map
choice
less than desirable.
What I'm proposing here is a simple customization to the XStreamPersister
that
allows plugins to register converters and aliases for their objects.
This is probably needed by Sampo for the stored query configuration, and I
would also
like to benefit from it.
The interface would be simple:
XStreamPersisterInitializer {
/**
* Allows XStream customizations. Plugins can use this to add aliases and
* custom converters for their own configuration objects
*/
void init(XStream xs);
}
This is pretty small, so not sure if a GSIP is required, but if you feel
like it is,
let me know.
Feedback welcomed
Cheers
Andrea
