Interface IAllocatorSynchronization

public interface IAllocatorSynchronization

This is a callback interface that can be used to synchronize store allocation structures. It has been conceived to allow two RWStores to maintain the in-memory FixedAllocators w/o the need to initialize from the root block on each commit. The implementing instance would be passed to a WriteCache.FileChannelScatteredWriteCache and the callbacks made from resetRecordMapFromBuffer.
