Method Details

initialize

public void initialize(SizeString constraintAnnotation)

Initializes an instance.

Specified by:

initialize in interface jakarta.validation.ConstraintValidator<SizeString, String>

isValid

public boolean isValid(String value,
 jakarta.validation.ConstraintValidatorContext context)

Checks if a string is allowable size.

a string is valid if the value is null or it's size is within min and max.

empty ("") is also valid.
Blank is allowed because it's supposed to be used for fields in record, which accepts values from external. HTML (and maybe others) cannot tell difference between blank and null for number values. Otherwise we also want the information whether the empty value is submitted (=blank) or not (=null).
