Working with Ruby 1D arrays from Ruby package

This article provides an introduction to cross-technology handling of one-dimensional 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.

With Javonet you can interact with arrays from Ruby package like they were available in Ruby 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 Ruby 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 Ruby:

Get element of an Ruby 1D array from Ruby package

In the snippet above, get1DArray method is used to get reference to 1D array from Ruby package. Method getIndex is used to get element from the array.

Set element of an Ruby 1D array from Ruby package

In the snippet above, get1DArray method is used to get reference to 1D array from Ruby package. Method setIndex is used to set element of the 1D array. First argument is index, second argument is new value.

Get size of an Ruby array from Ruby package

In the snippet above, get1DArray method is used to get reference to 1D array from Ruby package. Method getSize is used to get number of elements 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.
