unchecked_key_lookup(key, lookup_invocation, merge) click to toggle source

Performs a lookup with the assumption that a recursive check has been made.

@param key [LookupKey] The key to lookup @param lookup_invocation [Invocation] The current lookup invocation @param merge [MergeStrategy,String,Hash{String => Object},nil] Merge strategy, merge strategy name, strategy and options hash, or nil (implies “first found”) @return [Object] the found object @throw :no_such_key when the object is not found
