Class ValidatedValueUnwrapper<T>

java.lang.Object

org.hibernate.validator.spi.valuehandling.ValidatedValueUnwrapper<T>

Type Parameters:

T - the type which can be unwrapped by a specific implementation. The value for this type parameter must either resolve to a non-parameterized type (i.e. because the type is not using generics or because the raw type is used instead of the generic version) or all of its own type parameters must be unbounded wildcard types (i.e. <?>).

Direct Known Subclasses:

TypeResolverBasedValueUnwrapper

public abstract class ValidatedValueUnwrapper<T>
extends Object

Implementations unwrap given elements prior to validation.

Unwrapper implementations can be registered when bootstrapping a validator or validator factory. Note that when more than one unwrapper implementation is suitable to unwrap a given element, it is not specified which of the implementations is chosen.

Implementations must be thread-safe.
