All Implemented Interfaces and Traits:

jakarta.validation.ConstraintValidator<NotEmptyWhenNullableConstraint, Collection>

@CompileStatic
class NotEmptyWhenNullableConstraintForCollectionValidator
extends Object
implements jakarta.validation.ConstraintValidator<NotEmptyWhenNullableConstraint, Collection>

Validates if Collection is empty.

Null Collections are ignored (reported as valid).

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