org.syncany.database.dao.DatabaseXmlSerializer

public class DatabaseXmlSerializer
extends java.lang.Object

Serializes a MemoryDatabase or a list of DatabaseVersions to an XML-based file format, using a Transformer to compress/encrypt the file before writing, and to decompress/decrypt it before reading.

The class offers a variety of save() to serialize and store a memory database to a file, and several load() methods to load them from disk.

It uses a DatabaseXmlWriter to write XML files to disk and DatabaseXmlParseHandler to parse them while reading.
