  • The versionTag assists in making changes to the extension or any objects that implement YapDatabaseRelationshipNode.

    For example, say you have existing objects that implement the YapDatabaseRelationshipNode protocol. And you decide to add additional relationship connections from within the yapDatabaseRelationshipEdges method of some of your objects. All you have to do is change the versionTag. And next time you run the app, the YapDatabaseRelationship extension will notice the different versionTag, and will then automatically remove all protocol edges from the database, and automatically repopulate its list of protocol edges by enumerating the nodes in the database.
