Multiple meanings of "multiple" keyword

[e-grigorov]

I just realized that I am mapping semantically different data containers with the same keyword - multiple. For example:

• Java array
• java.util.Collection
• java.util.List
• java.util.Set

What is the correct mapping from your point of view?

Hi @e-grigorov
You are right, the DSL does not make any separation between these different container types.What would speak against putting this information into the mapping model for the device ?
I can imagine that there is a Functional Item Mapping file , that maps the (abstract) FB to the platform-specific Functional Item platform.

[e-grigorov]

The mapping file is a platform/generator specific and it's possible to cover almost everything. To me, the question is: is it a platform specific feature? Does it mean that the pure Java generator has to do the same?

From the Vorto modelling perspective, I wouldnt necessarily care if a multiple property is of type collection or array. This is implementation/platform specific. In the platform, I would need this information in order to process the device data correctly. The platform mapping, e.g. FunctionalItems would map this concrete to FI Basic types. The FI Generator would use this information and generate the Java source code.

Does it mean that the pure Java generator has to do the same?
If the Java Generator belongs to the same platform, then yes.
