Overview

Bolt 4.x handler for the pre-4.4 wire form. The driver negotiates it for 4.2 and 4.3 (see ProtocolVersionHandler); 4.4's wire additions (imp_user, the ROUTE map form) live in the V44 subclass, which every 5.x handler descends from.

Instance Method Details

#build_route(routing_context, bookmarks, database, _imp_user) ⇒ Object

ROUTE's third field is the target database as a bare string (or null for the home db). 4.4 changed it to a {db, imp_user} map — V44 overrides this; imp_user is unused here.
