Hi & wait a sec, you cannot just "let the other methods unimplemented", the code will not compile. All interface methods must be implemented, the bodies of void methods can be empty, others and can return nulls and 0's or throw exceptions, sure, but that seems confusing.
It seems simpler to have an interface with one method than to explain that the resolver is a Map, but not really, and that, today, only this here methods needs to be implemented. Or am I missing something?

On the other hand, if the resolve method guarantees that it will only use the get() method from the Map interface, the user is free to let the other methods unimplemented. The hint could be included in the javadoc, this should be enough for the minority of users interested in implementing a custom variable resolution.
