Method Detail

initialize

public void initialize(Annotation wrapper)

Specified by:

initialize in interface javax.validation.ConstraintValidator<Annotation,Collection<?>>

isValid

public boolean isValid(Collection<?> collection,
              javax.validation.ConstraintValidatorContext context)

Specified by:

isValid in interface javax.validation.ConstraintValidator<Annotation,Collection<?>>

setValidatorFactory

public void setValidatorFactory(javax.validation.ValidatorFactory factory)

unwrapConstraints

protected Annotation[] unwrapConstraints(Annotation wrapper)

createConstraintDescriptor

protected javax.validation.metadata.ConstraintDescriptor createConstraintDescriptor(Annotation constraint)

Note: The member argument of the ConstraintDescriptorImpl constructor is set to null, which may cause problems in some specific situations.

The problem is that it's not possible to access the validated "member" (field, method, constructor) from the validator context (or just don't know how). However, this "member" argument is currently (HV v5.0.1) used only to determine type of the constraint in some ambiguous situations (see ConstraintDescriptorImpl.determineConstraintType(java.lang.reflect.Member, java.lang.annotation.ElementType, boolean, boolean)). It seems that it's not necessary for "normal" validators and everything works fine. But to be honest, I'm not sure which specific types of validators will fail with this.

Parameters:

constraint - The constraint annotation to create descriptor for.

categorizeValidatorsByType

protected <T extends javax.validation.ConstraintValidator<?,?>> Map<Class,Class<? extends T>> categorizeValidatorsByType(List<Class<? extends T>> validatorClasses)

determineTargetType

protected Class<?> determineTargetType(Class<? extends javax.validation.ConstraintValidator<?,?>> validatorClass)

cache

protected Map<Class,javax.validation.ConstraintValidator> cache()

getCachedValidator

protected javax.validation.ConstraintValidator getCachedValidator(Class<?> type)

findAndInitializeValidator

protected javax.validation.ConstraintValidator findAndInitializeValidator(Class<?> type)

readMessageTemplate

protected String readMessageTemplate(Annotation constraint)

createMessage

protected String createMessage(javax.validation.metadata.ConstraintDescriptor descriptor,
                   Object value)
