Module: Axn::Mountable::MountingStrategies::Step::CallCollisionGuard

Defined in:
lib/axn/mountable/mounting_strategies/step.rb

Overview

Catches a def call written after steps were declared (the reverse order). Prepended to the singleton class — rather than define_singleton_method(:method_added) — so it composes with (and supers into) any method_added the class already defined. It fires only once the orchestrator marker is set, i.e. on a class that generated its own step #call; a mounted child action that merely inherits the marker-less host (e.g. an inherit: step whose ClassBuilder subclasses the host) defines its own #call without tripping it.
