io.micronaut.validation.validator.constraints

Interface ConstraintValidator<A extends Annotation,T>

Type Parameters:

A - The annotation type

T - The supported validation types

All Superinterfaces:

ConstraintValidator<A,T>

All Known Subinterfaces:

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

Functional Interface:

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

@Indexed(value=ConstraintValidator.class)
 @FunctionalInterface
public interface ConstraintValidator<A extends Annotation,T>
extends 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 Detail

VALID

static final ConstraintValidator VALID

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

Method Detail

isValid

boolean isValid(@Nullable
                T value,
                @NonNull
                AnnotationValue<A> annotationMetadata,
                @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,
                        ConstraintValidatorContext context)

Specified by:

isValid in interface ConstraintValidator<A extends Annotation,T>
