Declaring type: MapEntry<K, V>
Namespace: System.Collections.Generic
Assembly: Raven.Core.dll
Source file: MapEntry.rvn
Transforms a present value once and writes back the result.
A synchronous replacement callback; skipped when absent.
This reusable locator, including when absent.
The returned value wins over callback writes, and recreates a key removed by the callback on maps supporting removal. A callback exception prevents this helper's write; reference mutations and other callback effects remain. Chained calls independently resolve current state.
