Class DatabaseVersion

java.lang.Object

org.syncany.database.DatabaseVersion

public class DatabaseVersion
extends java.lang.Object

The database version represents an incremental addition to the local database of a client. A user's MemoryDatabase consists of many incremental database versions.

A DatabaseVersion is identified by a DatabaseVersionHeader, a combination of a VectorClock, a local timestamp and the original client name.

The database version holds references to the newly added/removed/changed PartialFileHistorys as well as the corresponding FileContents, ChunkEntrys and MultiChunkEntrys.

The current implementation of the database version keeps all references in memory.
