ResolvableAttribute class final

A string attribute of a constraint, such as the regular expression of @Matches, passed as an argument of a field error.

It is a message code of its own (the string itself), so a MessageSource may translate it: the key \d{5}=five digits turns must match {2} into must match five digits. When no key matches, the plain string is used. The validator creates it; applications never do. Spring's SpringValidatorAdapter.ResolvableAttribute.

// The arguments of an @Matches(r'\d{5}') error:
// [field, flags, ResolvableAttribute(r'\d{5}')]
