Interface ConfigValidator<T, A extends Annotation>

public interface ConfigValidator<T, A extends Annotation>
A config validator is used to read a custom validation annotation from a config field and validate the value so it for example matches an int range. Validators are applied when a config is read from a file. They are not applied if a server sends a config, and they'll not validate the default value.
