  Use this to request a typed object such as an interface for setting properties or getting status from the appropriate layer in the channel stack. If a layer supports returning the requested object, it returns it. If not, it delegates the call down to the next layer in the stack. If it gets to the bottom of the stack and no channel layer supported the requested object, then the method returns null.

  You must implement whenever you implement a channel factory. is an excellent way to communicate information along the channel factory stack without having to know what channel factories are below you, or what channel factories above you are interested in performing queries. Define interfaces for people to query on for any interesting information you have. Whenever you do not recognize the type argument for , delegate down to the next channel factory in the stack or return null if you are creating a new transport channel at the bottom of the stack.

  Returns a typed object requested, if present, from the appropriate layer in the channel stack.

  The typed object requested, if it is present, or null if it is not.

  The typed object for which the method is querying.
