Iterate over array from Ruby package in GoLang

This article shows how to iterate over array from called technology.

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.

Custom Ruby package with array 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 GoLang library.

Snippet below represents the sample code from Ruby package that has methods which return or process the arrays:

def get_1d_array
  return ["one", "two", "three", "four", "five"]

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

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

Iterate array from Ruby package in GoLang

With Javonet SDK it is possible to iterate over array from called technology and invoke methods on its elements.

This snippet doesn't support selected combination of technologies.

In the snippet above, get1DArray method is used to get reference to 1D array from Ruby package. This reference can be used to iterate over array's elements and optionally invoke methods on the elements.

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.
