lib/ldclient-rb/impl/event_factory.rb

Overview

Event constructors are centralized here to avoid mistakes and repetitive logic. The LDClient owns two instances of EventFactory: one that always embeds evaluation reasons in the events (for when variation_detail is called) and one that doesn’t.

Note that these methods do not set the “creationDate” property, because in the Ruby client, that is done by EventProcessor.add_event().
