Class DefaultConstraintValidators

java.lang.Object

io.micronaut.validation.validator.constraints.DefaultConstraintValidators

All Implemented Interfaces:

ConstraintValidatorRegistry

@Singleton
@Introspected
public class DefaultConstraintValidators
extends Object
implements ConstraintValidatorRegistry

A factory bean that contains implementation for many of the default validations. This approach is preferred as it generates fewer classes and smaller byte code than defining a validator class for each case.

Since:

1.2
