public final class LaissezFaireSubTypeValidator extends PolymorphicTypeValidator.Base
PolymorphicTypeValidator used unless explicit one is constructed.
Does not do any validation, allows all subtypes. Only used for backwards-compatibility
reasons: users should not usually use such a permissive implementation but use
allow-list/criteria - based implementation.PolymorphicTypeValidator.Base, PolymorphicTypeValidator.Validity| Modifier and Type | Field and Description |

PolymorphicTypeValidatorTypeResolverBuilder is needed. Intent is to allow early determination
of cases where subtyping is completely denied (for example for security reasons),
or, conversely, allowed for allow subtypes (when base type guarantees that all subtypes
are known to be safe). Check can be thought of as both optimization (for latter case)
and eager-fail (for former case) to give better feedback.validateBaseType in class PolymorphicTypeValidator.Basectxt - Configuration for resolution: typically will be DeserializationConfigbaseType - Nominal base type used for polymorphic handling: subtypes MUST be instances

Validator may be able to
determine validity of eventual type (and return PolymorphicTypeValidator.Validity.ALLOWED or
PolymorphicTypeValidator.Validity.DENIED) or, if not able to, can defer validation to actual
resolved type by returning PolymorphicTypeValidator.Validity.INDETERMINATE.
Validator may also choose to indicate denial by throwing a JsonMappingException
(such as InvalidTypeIdException)
