C# Класс SIL.FieldWorks.FDO.Infrastructure.Impl.SharedXMLBackendProvider

An XML file-based backend provider that allows multiple applications to access the same project simultaneously. It uses memory mapped files to maintain a shared commit log that all applications use to update their state to reflect changes made by other applications. The commit log is implemented as a circular buffer of commit records. A single peer is responsible for updating the XML file.

GetMetadata ( MemoryMappedViewStream stream ) : CommitLogMetadata
GetUnseenForeignChanges ( CommitLogMetadata metadata, List &foreignNewbies, List &foreignDirtballs, List &foreignGoners ) : bool

Gets all unseen foreign changes from the commit log. The metadata should be saved after calling this method, because inactive records might have been purged.
