SmartValidator class abstract interface

A Validator that can check only the constraints of some validation groups.

Groups let one class carry rules for different situations: an id that must be empty on create and set on update, checks that only run before an order is shipped. BeanValidator is the implementation; applications receive it rather than write one. The framework calls validateWithGroups when @Validated([OnUpdate]) names groups, and so do DataBinder.validate and ValidationUtils.invokeValidator when they are given groups.

// Check only the constraints declared with groups: [OnUpdate].
final errors = BeanPropertyBindingResult(form, 'signup');
validator.validateWithGroups(form, errors, [OnUpdate]);

Spring (Java):

SmartValidator validator = new LocalValidatorFactoryBean();
Errors errors = new BeanPropertyBindingResult(form, "signup");
validator.validate(form, errors, OnUpdate.class);

Implemented types

• Validator

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

supports(Object target) → bool

Whether this validator knows how to check target; usually a type test such as target is SignupForm.

inherited

toString() → String

A string representation of this object.

inherited

validate(Object target, Errors errors) → void

Checks target and records every problem in errors, with Errors.rejectValue for a field or Errors.reject for the whole object. Records nothing when target is valid; does not throw for invalid data.

inherited

validateWithGroups(Object target, Errors errors, List<Type> groups) → void

Checks target against the constraints of groups only and records the problems in errors.

Operators

operator ==(Object other) → bool

The equality operator.
