      • requiredKeys

        public abstract scala.collection.immutable.Seq<java.lang.String> requiredKeys()

        Implementers are free to define what makes Config entry compatible or not. We do provide some pre-build checks tough: JoinConfigCompatChecker.exists and JoinConfigCompatChecker.fullMatch

        Parameters:
        toCheck - - the Config instance to be checked
        actualConfig - - the Config instance containing the actual values
        Returns:
        a ConfigValidation. Can be Valid or Invalid, the later must contain a descriptive list of error messages.
