GroupByMapNode<'K, 'V, 'G> (Mibo)

GroupByMapNode<'K, 'V, 'G> Type

Namespace: Mibo.Adaptive
Assembly: Mibo.Adaptive.dll
Base Type: obj
All Interfaces: IMapSinkRegistry , IAdaptiveMap<'G, amap<'K, 'V>> , IDisposable , IAdaptiveObject , IMapDeltaSink<'K, 'V>

Groups the entries of an adaptive map by a computed key (the node behind AMap.groupBy). The output entries are live adaptive maps (GroupMapChildNode<'K,'V>); group-content changes reach the consumers through the children (their deltas and versions), so the output map's version moves only for group add/remove. A group disappears when it becomes empty (removed at the next drain); a key whose value changes group is moved between children.
