Method Detail

initialize

public void initialize(ConstraintDescriptor<C> constraintDescriptor,
                       HibernateConstraintValidatorInitializationContext initializationContext)

Description copied from interface: HibernateConstraintValidator

Initializes the validator in preparation for ConstraintValidator.isValid(Object, ConstraintValidatorContext) calls. It is an alternative to ConstraintValidator.initialize(Annotation) method. Should be used if any additional information except annotation is needed to initialize a validator. Note, when using HibernateConstraintValidator user should only override one of the methods, either HibernateConstraintValidator.initialize(ConstraintDescriptor, HibernateConstraintValidatorInitializationContext) or ConstraintValidator.initialize(Annotation). Both methods will be called during initialization, starting with HibernateConstraintValidator.initialize(ConstraintDescriptor, HibernateConstraintValidatorInitializationContext).

Specified by:

initialize in interface HibernateConstraintValidator<C extends Annotation,T extends TemporalAccessor & Comparable<? super T>>

Parameters:

constraintDescriptor - a constraint descriptor for a given constraint declaration

initializationContext - an initialization context for a current ConstraintValidatorFactory

isValid

public boolean isValid(T value,
                       ConstraintValidatorContext context)

Description copied from interface: ConstraintValidator

Implements the validation logic. The state of value must not be altered.

This method can be accessed concurrently, thread-safety must be ensured by the implementation.

Specified by:

isValid in interface ConstraintValidator<C extends Annotation,T extends TemporalAccessor & Comparable<? super T>>

Parameters:

value - object to validate

context - context in which the constraint is evaluated

Returns:

false if value does not pass the constraint

getEffectiveTemporalValidationTolerance

protected abstract Duration getEffectiveTemporalValidationTolerance(Duration absoluteTemporalValidationTolerance)

Returns the temporal validation tolerance to apply.

getReferenceValue

protected abstract T getReferenceValue(Clock reference)

Returns an object of the validated type corresponding to the current time reference as provided by the ClockProvider.

isValid

protected abstract boolean isValid(int result)

Returns whether the result of the comparison between the validated value and the time reference is considered valid.
