使用Ninject国际奥委会更换工厂 [英] Using Ninject IOC to replace a factory
问题描述
我有一个解析器内的工厂方法。从本质上讲,我加载一个令牌我仰望的处理程序令牌,或者通过对默认处理程序下降。我实现了这是一个开关
和一个词典<字符串类型>
但是这两种方法需要我来存储映射其他地方比处理程序类。
I've got a factory method inside a parser. Essentially as I load a token I look up the handler for that token, or drop through to the default handler. I've implemented this as a switch
and as a Dictionary<string,Type>
but both approaches require me to store the mapping somewhere else than the handler class.
我们正在使用Ninject为国际奥委会等我我也可以用做
We are using Ninject for IOC and so I've realized I can also do it using
kernel.Get<ITokenHandler>(tokenName);
但是,这并不救我存储在什么记号处理程序的信息,可以处理在2个地点。有没有一种方法,我可以装点处理程序,以便这一被自动映射?
but that doesn't save me storing the information on what token the handler can deal with in 2 locations. Is there a way I can decorate the handler so this gets mapped automatically?
推荐答案
如果我正确地按照你的问题,这听起来像要检索名为绑定。你没有提到你使用的是什么版本的Ninject,但基于您的代码段,我猜你正在使用Ninject 2.0。如果是这样的话,那么我认为这将足以为你的模块中绑定:
If I follow your question correctly, it sounds like you want to retrieve a named binding. You didn't mention what version of Ninject you are using, but based on your code snippet, I am guessing you are using Ninject 2.0. If that's the case then I would think this would suffice for your binding in your module:
Bind<ITokenHandler>().To<YourConcreteTypeHere>().Named(tokenName);
您尽可能多的具体类型绑定到相同的接口和名称区分它们,然后用检索它们你已经在你的问题中指定的确切语法。
You bind as many concrete types to the same interface and differentiate them by name, and then retrieve them using the precise syntax you've specified in your question.
如果我失去了一些东西的关键,让我知道。
If I am missing something key, let me know.
