Public Methods

override_method(*symbols, &block)

A clean way to override methods without resorting to alias_method. The original method can be called with super().

This works by giving the current class two anonymous base classes: one containing the original method, and one containing the new method. Thus, the original method must NOT make a call to super().

  class Foo
    def foo
      puts "foo!"
    end
    override_method :foo do
      def foo
        puts "foo 2!"
        super()
      end
    end
    override_method :foo do
      def foo
        puts "foo 3!"
        super()
      end
    end
  end
  Foo.new.foo #=> foo 3!
              #=> foo 2!
              #=> foo 1!

symbols	a list of symbols to override
