JRuby Akka Integration
To use Akka in JRuby, we’ll follow along the same lines as we did in Java. The main difference is we’ll be able to benefit from JRuby conciseness. We’re already familiar with the capabilities of Akka and its powerful API from Chapter 8, Favoring Isolated Mutability. Let’s jump right into implementing the design in Coordinating Actors for the file size program in JRuby. Remember, we need a bunch of message types, two actor types, and some main code to exercise these. Let’s start with the message types first:
| polyglotActors/jruby/FileSize.rb | |
| | class RequestAFile; end |
| | |
| | class FileSize |
| | attr_reader :size |
| | def initialize(size) |
| | @size = size |
| | end |
| | end |
| | |
| | class FileToProcess |
| | attr_reader :file_name |
