Reimplemented from kdb::KDB.

int kdb::tools::merging::MergingKDB::synchronize	(	KeySet &	returned,
		std::string const &	keyname,
		ThreeWayMerge &	merger
	)

virtual

Synchronizes the file with the supplied KeySet.

If a conflict occurs during set, the supplied merger is used to resolve the conflict. If the conflict cannot be solved, an exception is thrown. If the KeySet was successfully written (either by merging or due the absence of a conflict) the supplied KeySet is updated with the new content of the file.
