Instance Method Details

#event_name ⇒ Object

# File 'lib/hecks/bluebook/behaviour/policy.rb', line 14

def event_name = Naming.unqualified(@on_event)

#event_qualifier ⇒ Object 



12
 
# File 'lib/hecks/bluebook/behaviour/policy.rb', line 12

def event_qualifier = Naming.qualifier(@on_event)

#fans_out? ⇒ Boolean

WHETHER THIS POLICY FANS OUT — for_each names a query, and a non-empty one turns a single reaction into one dispatch per row the query answers. Read by the interpreter that runs the fan-out and by the property that checks it dispatched once per row.

Returns:

  • (Boolean)

# File 'lib/hecks/bluebook/behaviour/policy.rb', line 20

def fans_out? = !@for_each.to_s.empty?

#for_each_route(default_domain) ⇒ Object

THE FAN-OUT QUERY'S ROUTE, split the way the runtime runs it: [query_domain, aggregate_name, query_name]. The query runs against the triggering event's OWN domain unless for_each names one ("Domain::Aggregate.query"). Deliberately independent of across/target_domain, which name where trigger fires, not where the fan-out's own query runs.

def for_each_route(default_domain)
  path, query_name = @for_each.to_s.split(".", 2)
  domain, aggregate = path.to_s.include?("::") ? path.split("::", 2) : [default_domain.to_s, path]
  [domain, aggregate, query_name]
end

#guarded? ⇒ Boolean

WHETHER THIS POLICY IS GUARDED — a non-empty where decides whether the policy fires at all, read against the triggering event's own payload.

Returns:

  • (Boolean)

def guarded? = !@where.to_s.empty?

#hecks_name ⇒ Object

The BLUEBOOK's name for this construct, asked the same way of a class that has crossed over and of an IR object that has not. Collapses into Construct when this one crosses.
