Module: Minitwin::Initialization

Included in:
Minitwin
Defined in:
lib/minitwin/initialization.rb

Overview

Instance construction and low-level helpers used by the DSL-generated accessors. Filters unknown keys on initialize and seeds nested block properties so that validations on nested twins can run.
