PersistWhenValidto

PersistWhenValidto is a configuration option used in some data management and form-handling systems to govern how persistence relates to an entity’s validity window. In many data models, items include validity ranges defined by validFrom and validTo dates. PersistWhenValidto controls whether an item is allowed to be saved or updated once the current time falls outside that validity window or, conversely, whether preservation is allowed only within it.

Semantics can vary by implementation. When defined as a boolean, it typically expresses a simple rule: if the flag is true, persistence is permitted up to and including the validTo moment (or regardless of validity), and if false, persistence is restricted when the current time is past validTo. When provided as a predicate function, persistWhenValidto evaluates to true or false for a given object, often taking into account the object’s validFrom, validTo, current time, and possibly other business rules. This enables more flexible logic, such as allowing persistence when a record is marked as revalidated, even after validTo.

Common use cases include expiry-based data handling, licensing or subscription records, archival workflows, and forms that should not be saved once their validity period ends. It can help enforce data integrity by preventing saves of expired items or enabling conditional persistence during transitional states.

Implementation considerations include time zone handling, clock drift, and the interaction with other validity checks or validation rules. Because persistWhenValidto is not a universal standard, developers should consult framework-specific documentation or align its behavior with their domain’s data-retention and business rules.
