Module: Hecks::Bluebook::Behaviour::Indexed

Included in:
Aggregate, Command, Entity, PortOperation
Defined in:
lib/hecks/bluebook/behaviour/traits.rb

Overview

A CONSTRUCT THAT ANSWERS FOR ITS OWN DECLARATIONS BY NAME.

Indexed once, since the declarations are final by the time the construct exists — every dispatch asks these finders by name, and a linear scan repeated on every call was doing work the declared shape had already settled at boot.

index_by_name takes the collections to index rather than naming them, because WHICH collections a construct has is exactly the part that differs: an aggregate has five, an entity three, a command one.

Instance Method Details

#attribute(named) ⇒ Object 



63
 
# File 'lib/hecks/bluebook/behaviour/traits.rb', line 63

def attribute(named) = @attributes_by_name[named.to_sym]

#command(named) ⇒ Object 



64
 
# File 'lib/hecks/bluebook/behaviour/traits.rb', line 64

def command(named)   = @commands_by_name[named.to_s]

#index_attributes(attributes) ⇒ Object

Keyed by SYMBOL — an attribute is asked for by its declared symbol name everywhere in the runtime.

# File 'lib/hecks/bluebook/behaviour/traits.rb', line 51

def index_attributes(attributes)
  @attributes_by_name = attributes.to_h { |held| [held.name, held] }
end

#index_by_hecks_name(collection) ⇒ Object

Keyed by STRING and by hecks_name — a command, query or value object is a construct whose Ruby name is something else entirely (a constant path, or nothing at all for an anonymous class), so the DECLARED name is the only one worth indexing.
