The title of the contest subject is not quite precise but addresses the %Library.classes involved.
What is meant is officially named Class Query and is dating back to the early days of Caché.
CLASS is used because it is embedded in a COS class.
Though there is a precise description in the official documentation it remains rather abstract.
My tutorial should guide you step-by-step through a simple example in COS to make it tangible to you

In Studio, I had a set of nice Assist Functions to create correct code..

Do they exist in some similar way also in VSCcode ?

Same for SOAP wizard?

For quite some time I am bored by slowly starting Docke Demos from OEX.
I type

docker-compose up - d

and after a few seconds

docker-compose logs

And I just see ISC Agent was started and is hanging around
No IRIS instance is up yet.

The similarity between JSON objects + arrays and Globals in IRIS or Caché is evident.
With small and medium size JSON objects navigation across %Dynamic Objects is comfortable.
But with large and/or deep cascaded objects it becomes a challenge.

The presented tool offers 3 variants

• loading an already existing %Dyamic object or Array into a global of your choice
• loading a %Stream containing a JSON object into a global of your choice
• loading an external File containing a JSON object into a global of your choice

Some technical background information

There is not just one class in this package: rcc.gstream.cls but also rcc.gstreamT.cls

While rcc.gstream works with direct access to the stream globals, the *T version uses
a Process Private Global (PPG) as Temporary storage.
using SELECT * FROM RCC.gstreamT WHERE RCC.useT('^jpgS')=1 and similar.
