Constructor Detail

PartValidator

protected PartValidator(Function<A,String> zoneIdExtractor,
                        BiFunction<T,ZoneId,P> partExtractor,
                        Function<A,BiPredicate<P,ClockProvider>> partPredicateExtractor)

Creates a new validator.

Parameters:

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

partExtractor - A function that extracts a part from a TemporalAccessor.

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

PartValidator

protected PartValidator(Function<A,String> zoneIdExtractor,
                        Function<T,P> partExtractor,
                        BiFunction<T,ZoneId,ZonedDateTime> zoneIdApplier,
                        Function<ZonedDateTime,P> zonedDateTimePartExtractor,
                        Function<A,BiPredicate<P,ClockProvider>> partPredicateExtractor)

Creates a new validator.

This constructor is a specialization of PartValidator(Function, BiFunction, Function) that uses a part extractor that does the following:

 return zoneId == null
         ? partExtractor.apply(value)
         : zonedDateTimePartExtractor.apply(zoneIdApplier.apply(value, zoneId))
 

This can be used for types that use zones like OffsetDateTime.

Note: to prevent duplicating arguments, use PartValidator.ForZonedDateTime for ZonedDateTime,

Parameters:

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

partExtractor - A function that extracts a part directly from a TemporalAccessor.

zoneIdApplier - A function that applies a zone id to a TemporalAccessor, resulting in a ZonedDateTime. The result should represent the same instant.

zonedDateTimePartExtractor - A function that extracts the part from a ZonedDateTime.

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