EventVisibilityResolver class

Decides which cached events are visible, and why the others are not.

Visibility cannot be decided from a query result alone: the winner of a conflict domain and the NIP-09 deletion that covers an event can both sit outside it. Grouping only what a filter returned makes an old version look current whenever the filter excluded its successor, for example a read by event id. So the resolver runs one extra raw read to fetch that context, then classifies the candidates against it.

Implements CacheManager.loadHiddenEvents on top of a raw loader.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

toString() → String

A string representation of this object.

Static Methods

hiddenReasons(EventCacheStateRecord record, int now) → Set<HiddenEventReason>
