Annotation Type UnwrapValidatedValue

@Documented
 @Target(value={METHOD,FIELD,CONSTRUCTOR,PARAMETER})
 @Retention(value=RUNTIME)
public @interface UnwrapValidatedValue

When specified on properties (as represented by fields or property getters), parameters or executables, the value of the annotated element will be unwrapped from a container type prior to validation. This is useful when working with types such as JAXBElement or Optional where constraints should not apply to the container but to the wrapped element:

 @Size(max = 10)
 @UnwrapValidatedValue
 private JAXBElement<String> name;
 

For each type to be unwrapped, a corresponding ValidatedValueUnwrapper implementation must be registered.

Default:

true
