Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(*args, &block) ⇒ Object (private)

# File 'lib/active_factory.rb', line 416

def method_missing *args, &block
  if block
    @context.send *args, &block
  else
    @context.send *args
  end
end
