Interface Validator<T>

Type Parameters:

T - Validation target value type

All Superinterfaces:

Serializable

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Validator<T>
extends Serializable

Validate a value to check if it is valid.

For Validator.Validatable classes, validate(Object) method can be used to check if a value is valid. An Validator.ValidationException with an appropriate validation error message is thrown if the value is not valid.

Validator.ValidatorSupport interface should be implemented by classes which declare support for Validators.

This interface provides several static methods to obtain builtin Validators for common use cases.

Since:

5.0.0
