- oracle.toplink.essentials.descriptors.invalidation.CacheInvalidationPolicy

public class NoExpiryCacheInvalidationPolicy extends CacheInvalidationPolicy

PUBLIC: A cache invalidation policy in which no objects will expire. The only way for objects to become invalid in the cache is for them to be explicitly set to invalid through method calls on the IdentityMapAccessor. This is the default cache invalidation policy.

return NO_EXPIRY;
public boolean isInvalidated(oracle.toplink.essentials.internal.identitymaps.CacheKey key, long currentTimeMillis)
