inheritance - Returning a subclass from its base class in swift -

-

I am trying to return an instance of subclass to a method in a superclass so that I can do the method with chaining Can you use methods in both parent and child?

However, I'm getting an error "When I try to sort methods, there is no member of any other name in the baseclass" Here's my code: < Class = "class" class = "class" class = "class" class = "class" class = "class" class = "class" class = "class class class" Kids Class = Child Class Child Class. Some Chinese Meth (). Yue Chainable Mathides ()

It seems that the original series-enabled method is returning 'Return Self' instead of ChildClass BaseClass

I have also tried to do with generic and failed, this is what I have done: class base class Gt; {Some small Meth () - & gt; T {Return Self}} Class Child Class: Base Class & lt; ChildClass & gt; {Some Other Important Laws (FAQ) - & gt; ChildClass {Return Self}} Let babyCla Ss = child class childClass.SomeChainableMethod (). SomeOtherChainableMethoid ()

In this case, BaseClass someChainableMethod method, "BaseClassT is not convertible is".

If you change your code works self: : 

  Return type depending on the class Base class {func someChainableMethod () - & gt; Self {Return Self}} Class Child Class: Base Class {Fax Some Other Mible () - & gt; Let itself {return self}} Let childClass = childclass () let foo = childClass.someChainableMethod (). SomeOtherChainableMethod ()

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
