All Implemented Interfaces and Traits:

jakarta.validation.ConstraintValidator<NotBlankWhenNullableConstraint, String>

@CompileStatic
class NotBlankWhenNullableConstraintValidator
extends Object
implements jakarta.validation.ConstraintValidator<NotBlankWhenNullableConstraint, String>

Validates if String is blank.

Null values are ignored (reported as valid).

This constraint validator is very similar to the bean validation's NotBlank, but this one skips null values and does not report them as violations.
