Public Instance methods

This awesome piece of hackery implements action AOP.

The so-called aspects are simply methods that may yield the next aspect in the chain, this is similar to racks concept of middleware, but instead of initializing with an app we simply pass a block that may be yielded with the action being processed.

This gives us things like logging, caching, aspects, authentication, etc.

Add the name of your method to the trait[:wrap] to add your own method to the wrap_action_call chain.

@example adding your method

  class MyNode
    Innate.node '/'

    private

    def wrap_logging(action)
      Innate::Log.info("Executing #{action.name}")
      yield
    end

    trait[:wrap]
  end

methods may register themself in the trait[:wrap] and will be called in left-to-right order, each being passed the action instance and a block that they have to yield to continue the chain.

@param [Action] action instance that is being passed to every registered method @param [Proc] block contains the instructions to call the action method if any
