-
#after_any_lazies(maybe_lazies) ⇒ Object
private
Return a lazy if any of
maybe_lazies
are lazy, otherwise, call the block eagerly and return the result. -
#after_lazy(value, &block) ⇒ Object
private
Call the given block at the right time, either: - Right away, if
value
is not registered withlazy_resolve
- After resolvingvalue
, if it’s registered withlazy_resolve
(eg,Promise
). -
#lazy?(obj) ⇒ Boolean
True if this object should be lazily resolved.
-
#lazy_method_name(obj) ⇒ Symbol?
The method name to lazily resolve
obj
, or nil ifobj
’s class wasn’t registered wtih #lazy_resolve. -
#sync_lazy(value) ⇒ Object
private
Override this method to handle lazy objects in a custom way.
