Package io.micronaut.validation.validator.constraints

Interface ConstraintValidator<A extends Annotation,T>

Type Parameters:

A - The annotation type

T - The supported validation types

All Superinterfaces:

jakarta.validation.ConstraintValidator<A,T>

All Known Subinterfaces:

DecimalMaxValidator<T>, DecimalMinValidator<T>, DigitsValidator<T>, SizeValidator<T>

All Known Implementing Classes:

EmailValidator, PatternValidator

Functional Interface:

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

@Indexed(ConstraintValidator.class)
@FunctionalInterface
public interface ConstraintValidator<A extends Annotation,T>
extends jakarta.validation.ConstraintValidator<A,T>

Constraint validator that can be used at either runtime or compilation time and is capable of validation Constraint instances. Allows defining validators that work with both Hibernate validator and Micronaut's validator.

Unlike the specification's interface this one can uses as a functional interface. Implementor should not implement the ConstraintValidator.initialize(Annotation) method and should instead read the passed AnnotationValue.

Field Details

VALID

static final ConstraintValidator<Annotation,Object> VALID

A constraint validator that just returns the object as being valid.

Method Details

isValid

boolean isValid(@Nullable
 T value,
 @NonNull
 @NonNull io.micronaut.core.annotation.AnnotationValue<A> annotationMetadata,
 @NonNull
 @NonNull ConstraintValidatorContext context)

Implements the validation logic.

Implementations should be thread-safe and immutable.

Parameters:

value - object to validate

annotationMetadata - The annotation metadata

context - The context object

Returns:

false if value does not pass the constraint

isValid

default boolean isValid(T value,
 jakarta.validation.ConstraintValidatorContext context)

Specified by:

isValid in interface jakarta.validation.ConstraintValidator<A extends Annotation,T>
