su.onno.validation.ValidationErrors

public final class ValidationErrors
extends Object

Accumulates validation failures across all sources (declarative attribute constraints, custom BusinessRules) so the user sees every problem at once rather than one at a time. throwIfAny() raises a ValidationException when anything was collected.
