You mean that someone with special resolving requirements should provide a custom class that implements Map? That's doable I guess, and it does provide a unified API that is nice for those cases where the source data really is in a standard Map object (which will probably be the case 95% of the time). However for the other cases the user has to implement the Map interface which it's quite a lot of work. As the resolve method actually uses only the "get" method on the map it seems a shame to require the user to implement the full Map interface. And the get method takes an Object key and returns an Object result, whereas resolve always provides a String key and returns a String result. So using a map means using types far more generic than necessary; not fatal but not elegant.
