Subject [jira] [Commented] (SANDBOX-472) Transformer Registry
Date Mon, 25 Aug 2014 06:16:57 GMT


Benedikt Ritter commented on SANDBOX-472:

Hello [~yogu13],

I've looked into your lastest patch. The TransformerRegistry looks good! But where has the
TransformerRegistryTestCase gone? :) It is missing in your patch. Further more I currently
don't understand what you're trying to achieve with the TransformerRegistryLoader and the

I don't think that we need the loader. Having an object that handles transforming is maybe
a good thing. Although I'd just call it a TransformerBean. Can't we just pass the TransformerRegistry
to the TransformerBean? We can provide different implementations of the TransformerRegistry
(by extracting an interface), for example one that provide a fluent API for adding additional

Since I'd like to finally commit party of your hard work, may I ask you to create a patch
just containing the TransformerRegistry and the TransformerRegistryTestCase (and test transformers
if needed)? We can add that to the code base and then start working on the integration of
the registry from there on. WDYT?

Best regards and many thanks for your patience!

Beanutils1 has a functionality wherein all the converters are registered and are called when
conversion in value is required. This functionality is missing for BU2 project. I also saw
that BeanUtils1 uses WeakFastHashMap for this, which seems like is having issues across architectures
and did see few JIRA's on this. Wanted inputs if having a synchronized instance of WeakHashMap
wrapped in the TransformerRegsitry class and providing methods to register, deregister, restoreDefault,
lookup be desired?
