C# Class AcTools.LapTimes.LevelDbUtils.WriteBatch

WriteBatch holds a collection of updates to apply atomically to a DB. The updates are applied in the order in which they are added to the WriteBatch. For example, the value of "key" will be "v3" after the following batch is written: batch.Put("key", "v1"); batch.Delete("key"); batch.Put("key", "v2"); batch.Put("key", "v3");
