Module: TypeToolkit::AbstractInstanceMethodReceiver

Defined in:
lib/type_toolkit/abstract_method_receiver.rb

Overview

This module is included on a class whose instances can be receivers of calls to abstract methods.

Since abstract methods are removed at runtime (see TypeToolkit::DSL#abstract), attempting to call an unimplemented abstract method would usually raise a NoMethodError. This module uses method_missing to raise AbstractMethodNotImplementedError instead. @requires_ancestor: Kernel

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name) ⇒ Object

This #method_missing is hit when calling a potentially abstract method on an instance E.g. TheClass.new.maybe_abstract_method

(Symbol, ...) -> untyped
