Validate properties when creating the configuration instance

[Evandro Pomatti]

Hi

Is it possible to validate the value of properties when creating the config instance? I would like that the creation of a config instance fail upon the startup of the system if some properties are invalid.

For example, I have the following config:

public interface MyConfigs extends Config {
    @Key("myconfs.url")
    public URL url;
}

And I try to create a config instance with the following properties, using an invalid URL:

myconfs.url=xyz%$invalidurl

Can I validate it when calling "ConfigFactory.create()"? Or even simpler, validate an Integer number.

I read the documentation but I did not found any feature related to it. Did I miss anything?

Currently I have implemented a explicit call to each property that is mandatory, but it would be nice if the library did it for me so some code would be saved.

thanks!
