Module: Domainic::Command::Context::Behavior

Included in:
InputContext, OutputContext
Defined in:
lib/domainic/command/context/behavior.rb

Overview

A module that provides attribute management for command contexts. When included in a class, it provides a DSL for defining and managing typed attributes with validation, default values, and thread-safe access.

Thread Safety

The attribute system is designed to be thread-safe during class definition and inheritance. A class-level mutex protects the attribute registry during:

  • Definition of new attributes via the DSL
  • Inheritance of attributes to subclasses
