Annotation

@Documented
@Repeatable(value: NotEmptyWhenNullableConstraintList)
@Target(value: [FIELD, METHOD, PARAMETER, TYPE_USE, ANNOTATION_TYPE])
@Retention(value: RUNTIME)
@jakarta.validation.Constraint(validatedBy: [])
@interface NotEmptyWhenNullableConstraint

The annotated element must not be empty when it is not null.

Accepts Collection and Map types. Message interpolation key is org.klokwrk.lib.lo.validation.constraint.NotEmptyWhenNullableConstraint.message.

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