Constructor Detail

FieldValidator

protected FieldValidator(Function<A,TemporalField> fieldExtractor,
                         Function<A,String> zoneIdExtractor,
                         BiFunction<T,ZoneId,TemporalAccessor> zoneIdApplier,
                         Function<A,BiPredicate<Integer,ClockProvider>> fieldPredicateExtractor)

Creates a new validator.

If a ZoneId is available, the field will be extracted from the result of applying the given zoneIdApplier function to the value to validate. Otherwise it will be extracted from the value itself.

Parameters:

fieldExtractor - A function that extracts the field to validate from a constraint annotation.

zoneIdExtractor - A function that extracts the zone id from a constraint annotation.

zoneIdApplier - A function that applies a zone id to a TemporalAccessor, resulting in a TemporalAccessor with the zone id applied. The result is usually a ZonedDateTime but doesn't have to be. The result should represent the same instant.

fieldPredicateExtractor - A function that extracts a field predicate from a constraint annotation. This predicate will be called in BaseValidator.isValid(Object, ConstraintValidatorContext), with as arguments the field extracted from the value to validate and the ClockProvider returned by ConstraintValidatorContext.getClockProvider().

FieldValidator

protected FieldValidator(TemporalField field,
                         Function<A,String> zoneIdExtractor,
                         BiFunction<T,ZoneId,TemporalAccessor> zoneIdApplier,
                         Function<A,BiPredicate<Integer,ClockProvider>> fieldPredicateExtractor)

Creates a new validator.

If a ZoneId is available, the field will be extracted from the result of applying the given zoneIdApplier function to the value to validate. Otherwise it will be extracted from the value itself.

Parameters:

field - The field to validate.

zoneIdExtractor - A function that extracts the zone id from a constraint annotation.

zoneIdApplier - A function that applies a zone id to a TemporalAccessor, resulting in a TemporalAccessor with the zone id applied. The result is usually a ZonedDateTime but doesn't have to be. The result should represent the same instant.

fieldPredicateExtractor - A function that extracts a field predicate from a constraint annotation. This predicate will be called in BaseValidator.isValid(Object, ConstraintValidatorContext), with as arguments the field extracted from the value to validate and the ClockProvider returned by ConstraintValidatorContext.getClockProvider().
