Constant Summary collapse

BLACKLISTED_ARRAY_METHODS =

This module creates compiled delegation methods dynamically at runtime, which makes subsequent calls to that method faster by avoiding method_missing. The delegations may vary depending on the klass of a relation, so we create a subclass of Relation for each different klass, and the delegations are compiled into that subclass only.
