Examples of javax.validation.Validator.validateValue()

javax.validation.Validator.validateValue()
Validates all constraints placed on the property named propertyName of the class beanType would the property value be value
ConstraintViolation objects return null for {@link ConstraintViolation#getRootBean()} and {@link ConstraintViolation#getLeafBean()} @param beanType the bean type @param propertyName property to validate @param value property value to validate @param groups group or list of groups targeted for validation(default to {@link javax.validation.groups.Default}) @return constraint violations or an empty Set if none @throws IllegalArgumentException if beanType is null,if propertyName null, empty or not a valid object property or if null is passed to the varargs groups @throws ValidationException if a non recoverable error happensduring the validation process
