Continuous Release · Open Source · Grassroots Project · Optional. This repository provides SAP's style guides for coding. Programming languages enable us to say the same thing in different ways. While all of them may be correct, some may be more efficient, easier to understand, and more robust than others. Our style guides want to show up differences and guide you towards code that has a healthy balance between all of these qualities.

What is the recommended (modern) approach for reusing types between different classes?
SAP does not recommend to collect constants in an interface, calling it a loosy way of declaring:...

As the document you linked to says, you should not use an interface for constants because that way you are:
misleading people to the conclusion that constants collections could be "implemented".
Which is why they recommend to put constants into an
ABSTRACT FINAL class.
ABSTRACT means that this class as itself can not be instantiated (like an interface) and
FINAL that it can not be inherited from (unlike an interface). This clearly communicates to the user that this class only exists as a container for static things like
CLASS-METHODS and of course
So the same argument can be used against interfaces which do nothing but serve as a container for types. When you create an
INTERFACE for that sole purpose, then people might wonder how they are supposed to implement that interface. So you would put them into a
Another alternative which is still worth considering IMO (especially if you consider to use any of those types in database tables) is to use the good old ABAP Dictionary. It was invented for exactly that purpose: To serve as a directory for global types.
Unfortunately it doesn't allow you to organize types into namespaces (not unless you are working for SAP or a SAP partner who is able and willing to go through the bureaucracy to register a worldwide unique namespace for every product). So you have to make sure that each type you create has a proper prefix so people know which application it belongs to. But there is a character limit for dictionary type names, so you have to keep them short.
Using a class as a container for the types of each application solves that problem. The class serves as a namespace, so your type names no longer need to be system-unique.
I'm very new to scala and this is a more of a question of curiosity.
Let's say I have a class...

Looks impossible to me.
These kinds of Scala DSLs are essentially just chains of method calls without dots and parentheses:
I'm trying to pass a variable that is set on a component, to the parent component via a getter/setter in a service. The setter is applied correctly, but the getter returns undefined.
The below code was pulled out of another project I work on that does just fine with this code so I'm not sure why it isn't working here.
I simply just need to pass the pageTitle that is set on the child component, pass it to the parent component to display in its HTML.

You should implement the Service with Observables. A quick example would be something like this:
Suppose I have a project organized as follows:...

Here's my temporal solution since no one provided pythonic approach.
Folder structure looks like that:
