Static any language fields and properties from Ruby package

This article provides an introduction to cross-technology handling of static fields and properties.
Javonet allows you to reference and use modules or packages written in (Java/Kotlin/Groovy/Clojure, C#/VB.NET, Ruby, Perl, Python, JavaScript/TypeScript) like they were created in your technology. If have not yet created your first project check Javonet overview and quick start guides for your technology.

With Javonet you can interact with static field and properties from Ruby package like they were available in any language but invocation must be performed through Javonet SDK API.

Get/Set static any language field from custom Ruby package

With Javonet it is possible to reference any custom Ruby package and interact with public static fields and properties declared on types defined within that module almost the same as with any other any language library.

Snippet below represents the sample code from Ruby package which contains class with fields:

module TestClass
    class TestClass

        @@static_value = 3
        @public_value
        @private_value
        
        def initialize(public_value = 0, private_value = 0)
          @public_value = public_value
          @private_value = private_value
        end
    end
end
@@static_value = 3
@public_value
@private_value

def initialize(public_value = 0, private_value = 0)
  @public_value = public_value
  @private_value = private_value
end

It is possible to get one of the declared static fields from Ruby package using following any language code.

This uses in memory runtime bridging to load the Ruby package, and next retrieves reference to specific type and gets the static field. Result of the invocation is returned as regular any language value and can be used for further processing. It is possible to set one of the declared static fields from Ruby package using following any language code.

This uses in memory runtime bridging to load the Ruby package, and next retrieves reference to specific type, then sets and gets the static field. Result of the invocation is returned as regular any language value and can be used for further processing.

Get/Set static any language field from standard Ruby package

The same steps are required to get types and fields from framework Ruby package:

The same operation can be performed remotely by just changing the new Runtime Context invocation from in memory to tcp that will create and interact with your Ruby package objects on any remote node, container or service that hosts Javonet Code Gateway. This way you can preserve the same logic in your application and instantly switch between monolithic and microservices architecture without the need to implement the integration layer based on web services or other remote invocation methods.
