Package io.goobi.viewer.model.security.user

Class IpRangeCache

java.lang.Object

io.goobi.viewer.model.security.user.IpRangeCache

public class IpRangeCache
extends Object

Application-scoped cache for IpRange reads. See docs/superpowers/specs/2026-04-22-dao-access-cache-design.md.

Thread-safety and invalidation contract match io.goobi.viewer.model.security.LicenseTypeCache.

Staleness note on IpRange.licenses: the hydrated licenses collection on each cached IpRange can become stale after addLicense / updateLicense / deleteLicense writes (those writes do not invalidate this cache, because the relevant access-decision code paths go through the DAO for getLicenses(...) directly). Do not rely on cachedIpRange.getLicenses() for authorisation decisions.
