Working with n-D any language arrays from Ruby package

This article provides an introduction to cross-technology handling of multidimensional arrays. Data structures are one of the essential aspects of every piece of software. Any application constantly process various information, that very often require specific grouping and access strategies. This aspect is addressed by arrays and more advanced collection types. By using the Javonet framework, users gain ability to easily and effectively work with data structures originating from Ruby package. Every array from Ruby package is treated as reference.

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.
ith Javonet you can interact with arrays from Ruby package like they were available in any language but invocation must be performed through Javonet SDK API.

Custom Ruby package with arrays handling

With Javonet it is possible to reference any custom Ruby package and interact with arrays 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 that has methods which return or process the arrays:

module TestClass
    class TestClass

        def get_1d_array
          return ["one", "two", "three", "four", "five"]
        end
        
         def get_2d_array
           return [["S00", "S01"],["S10", "S11"]]
         end
        
        def add_array_elements_and_multiply(my_array, my_value)
          return my_array.sum * my_value
        end
    end
end
def get_1d_array
  return ["one", "two", "three", "four", "five"]
end

 def get_2d_array
   return [["S00", "S01"],["S10", "S11"]]
 end

def add_array_elements_and_multiply(my_array, my_value)
  return my_array.sum * my_value
end

Javonet SDK contains various methods to interact with arrays and consume the results in any language:

Get element of any language 2D array from Ruby package

In the snippet above, get2DArray method is used to get reference to 2D array from Ruby package. Method getIndex is used to get element from the array. Depending on calling technology there is one or more ways to get element from array.

Set element of any language 2D array from Ruby package

In the snippet above, get2DArray method is used to get reference to 2D array from Ruby package. Method setIndex is used to set element of the array.

Get size and rank of 2D array

In the snippet above, get2DArray method is used to get reference to 2D array from Ruby package. Method getSize is used to get number of elements of the array.
Method getRank is used to get number of dimensions of the array.

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.
