CreditCardValidator: Ensures the value is a plausible credit card number.
DateRangeValidator: Ensures the value falls within the inclusive range [start, end].
EmailValidator: Ensures the value is a validly formatted email address.

HasUppercaseValidator: Ensures the value contains at least one uppercase character.
LengthRangeValidator: Ensures the trimmed value's length (in Unicode code points) is contained in the range min, max.
MatchValidator: A special validator that checks whether two values are equal.
MaxLengthValidator: Ensures the value contains no more than max Unicode code points (runes).
MaxValidator: Ensures the number is less than or equal to max.
MinLengthValidator: Ensures the value contains no fewer than min Unicode code points (runes).
MinValidator: Ensures the number is greater than or equal to min.
ModelValidator<T>: Validates a whole model T: field checks, cross-field rules, conditions and rule-sets, reusing the package's value validators.
MultipleOfValidator: Ensures the number is a multiple of factor.
NegativeValidator: Ensures the number is strictly less than zero.
NumRangeValidator: Ensures the numeric value of the input is contained in the range min, max.
OddValidator: Ensures the number is odd (its remainder modulo 2 is one).
OneOfValidator: Ensures the value is one of the allowed values.
PastValidator: Ensures the value is in the past relative to clock.
PatternTextValidator: Base class for validators backed by a regular expression.
PatternValidator: Ensures the value matches a custom regular expression.
PhoneValidator: Ensures the value is a validly formatted phone number.
PositiveValidator: Ensures the number is strictly greater than zero.
PredicateValidator<T extends Object>: Builds a validator from a plain predicate — a one-off check without declaring a new class.
RangeValidator: Ensures the number is within the inclusive range [min, max].
RequiredValidator: Ensures the value is not empty and not whitespace only.
RuleBuilder<T>: Fluent builder for a single field's rule (see ModelValidator.ruleFor).
TextValidator: Base class for validators that operate on optional text (String?).
UrlValidator: Ensures the value is a validly formatted URL.
ValidationResult: The outcome of validating a model: which field failed with which messages.
Validator<T extends Object>: Base class for every validator in the package.
ValidatorGroup<T extends Object>: Groups several validators of the same type T and runs them in order.

Patterns

Extensions

PatternsValidation on Patterns: Builds a ready-made validator from any Patterns entry, so all 40+ formats are available as validators — not only the few with a named class.
StringCheck on String
ValidatorComposition on Validator<T>: Composition sugar for building a ValidatorGroup with the & operator.
