Interface Validator<T>

Type Parameters:
T - the type of the object to validate
All Known Implementing Classes:
JakartaValidationValidator
public interface Validator<T>
A validator for validating application-specific objects.

This interface is inspired on Spring's Validator mechanism. However Hawaii's validator mechanism uses it's own ValidationResult instead of Spring's Errors for returning validation errors.

Implementors should typically only implement validate(Object, ValidationResult) as other methods are already implemented using the interface's default methods.
