Validator Base Class

The abstract class TValidator is the base class from which all validator classes are derived.

TValidator is a validator for which all input is valid: Member functions TValidator::IsValid and TValidator::IsValidInput always return true, and TValidator::Error does nothing. Derived classes should override IsValid, IsValidInput, and Error to define which values are valid and when errors should be reported. Use TValidator as a starting point for your own validator classes if none of the other validator classes are appropriate starting points.
