Module: Neo4j::Driver::BookmarkManagers

Defined in:
lib/neo4j/driver/bookmark_managers.rb

Overview

Factory for the driver's default BookmarkManager. Mirrors org.neo4j.driver.BookmarkManagers#defaultManager — but with a Ruby keyword-arg surface instead of a config builder, matching the JRuby flavour's ext shim (lib/jruby/.../ext/bookmark_managers.rb).

The returned object is duck-typed: any value responding to

bookmarks                                  -> Set<Bookmark>
update_bookmarks(previous, new)            -> void

is a manager. Pass your own instance to Driver#session or Driver#execute_query via :bookmark_manager if you want a store backed by something other than the in-memory default (e.g. Redis); no inheritance or interface declaration needed.

initial_bookmarks — seed the manager with bookmarks the caller already has (e.g. from a persisted store). bookmarks_supplier — callable returning extra bookmarks to merge into every bookmarks call (lets external bookmark sources participate without being folded into the manager's own state). bookmarks_consumer — callable receiving the new bookmark snapshot after every successful update (lets external observers persist or forward bookmarks).
