public class HotRestartHiDensityNativeMemoryCacheRecordMap
extends HiDensityNativeMemoryCacheRecordMap

Hot Restart variant of HiDensityNativeMemoryCacheRecordMap.

All mutator actions are synchronized to make them visible to Hot Restart GC thread.

Eviction methods don't actually evict the record but only clear and dispose the value contained in the record.
