Javadoc
Initializes the validator in preparation for
#isValid(Object,ConstraintValidatorContext) calls.
It is an alternative to
#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
#initialize(ConstraintDescriptor,HibernateConstraintValidatorInitializationContext) or
#initialize(Annotation).
Both methods will be called during initialization, starting with
#initialize(ConstraintDescriptor,HibernateConstraintValidatorInitializationContext).
