I have a slough of domain entities (without interfaces) that largely encapsulate various algorithms for calculation, returning a double which needs to be rounded (or not). I am using NHibernate so public methods/properties are marked virtual.
I now have a requirement where rounding is applied to many of the methods according to a specific context. For example, when using the entity for one agency, we'd apply specific rules or perhaps for a certain report round according to a different set of rules. The methods themselves are very focused in responsibility so the entities are poised to do this fairly easily, and I think I can leverage DynamicProxy to do something like: double value = new Rounded().Instance(myInstance).MyCalculation(); Where 'Rounded' would generate a proxy and apply the appropriate interceptor for rounding rules and return the proxy. The only wall I have come up against is the inability to create proxies of existing class instances. Like I mentioned I don't have interfaces defined for the entities and before I go that route I wanted to see if anyone has dealt with a similar issue for contextualizing domain entities. Any ideas on approaches that might engage castle voodoo? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Castle Project Users" group.
