Runtime variable interpolation

[mmadson]

Is it possible to leverage Owner's variable expansion support to perform runtime variable interpolation on strings?

For example, say I have an owner interface that defines a property

public interface MyConfig extends Config {

    @DefaultValue("/root")
    String rootPath();
}

Would it be possible to do something like:

assertEquals("/root/some/other/text", myConfigInstance.interpolate("${rootPath}/some/other/text"));

assuming of course that the the default value for rootPath was not overridden during this test.

Thanks!

EDIT:

After taking a quick peek at the code, it looks like this would be pretty easy to support by adding a new method to the Accessible interface (or perhaps a new extension interface?) along with a corresponding @DeleGate method to the PropertiesManager class. If you like this idea, I can fork, impl and submit a pull request.

Hi @mmadson.

I like the idea, and I support your solution 👍

Feel free to fork and provide your implementation. Also write a unit test for it (patches without a unit tests are not accepted).

Thanks.

Luigi.
