Method Detail

validate

void validate(@Nullable
              Object target,
              Errors errors,
              Object... validationHints)

Validate the supplied target object, which must be of a type of Class for which the Validator.supports(Class) method typically returns true.

The supplied errors instance can be used to report any resulting validation errors.

This variant of validate() supports validation hints, such as validation groups against a JSR-303 provider (in which case, the provided hint objects need to be annotation arguments of type Class).

Note: Validation hints may get ignored by the actual target Validator, in which case this method should behave just like its regular Validator.validate(Object, Errors) sibling.

Parameters:

target - the object that is to be validated (can be null)

errors - contextual state about the validation process (never null)

validationHints - one or more hint objects to be passed to the validation engine
