MapEntry<K, V>

class MapEntry<K, V>

Namespace: System.Collections.Generic
Assembly: Raven.Core.dll
Source file: MapEntry.rvn

Inheritance: Object → MapEntry<K, V>

A reusable live key locator, not a borrowed storage reference or snapshot.

Retains the map and key. Each operation resolves current state through the map's comparer. No atomicity, synchronization or rollback is provided. Keys must obey the map's stability requirements.
