A TBase cluster consists of multiple CoordinateNodes, DataNodes, and GTM nodes. All user data resides in the DataNode, the CoordinateNode contains only metadata, the GTM for global transaction management. The CoordinateNodes and DataNodes share the same schema. Users always connect to the CoordinateNodes, which divides up the query into fragments that are executed in the DataNodes, and collects the results.

You cannot cast an instance of a parent to an instance of a child. That's not how it works.

You can cast an instance of a class in a variable of a parent type to the type of the child, as long as the variable is created as an instance of the child.

Your code is syntactically correct, and will increment Q_int by the required amount. The problem is that Q_int is initialised to "UUUU" and is not assigned a value on reset. And when you add anything to "UUUU", you get "UUUU".

The answer here is to either: Give Q_int and initial value: eg.

Typescript how to infer type from class constructor arguments

Asked 2021-Dec-27 at 03:54

I have a class definition that has typed arguments on the constructor. I want to reuse the argument type definition elsewhere without refactoring or extracting the definition from the class. How can I do this. below is an example with a GetProps type that I was suggested but doesn't actually work. I expect the const bp definition to throw an error because it is missing the derp field which is defined in the constructor.

Using type in template class of derived template class

Asked 2021-Dec-15 at 14:20

Try to implement the CRTP pattern. Therefore I created two template classes. With the first draft of only one template class PDerived everything is fine. But for my purpose in a bigger project I need two template classes. Which results in an error: All types of the PDerivced class are not found. But I have no idear why. In the following the is a minimalistic example.

In this example myType can not be found? If TDerived is no template class everything is fine. Is there some namespace needed?

If you want to refer to some templated stuff of your base class, you have to give the compiler a hint how to find it.

Base in the activate method is the class constructor. It is not an instance. And activate is an method on instances.

But since activate is an instance method, you can just use this instead.

Just replace Base with this and it works just fine.

If you are really sure that it holds TChild objects only and you won't add any other objects to it after the cast (List is read-only, not immutable), then you can just do an unchecked cast like this:

ANSWER

Answered 2021-Jun-11 at 11:46

This appears to be a mistake in the documentation. The generic parameter T is the return type of the constructor, so it should be the object type Sprite rather than the class type typeof Sprite.

I've submitted a PR to fix it: https://github.com/microsoft/TypeScript-Website/pull/1862

Update: The PR has been merged and the Constrained-mixins documentation now uses GConstructor istead of GConstructor.
