With this server, the methods are associated automatically with the XML-RPC server. A call to sample.some_method from an XML-RPC client would automatically be routed through to the instance method some_method made available from OurClass.

DRb stands for Distributed Ruby, and is a Ruby-only RPC library. On the surface, DRb doesn t appear to be too different from XML-RPC, but if you only need to talk between Ruby programs, it s a lot more powerful. Unlike XML-RPC, DRb is object-oriented, and connecting to a DRb server gives the client an instance of a class located on the DRb server. You can then use the methods made available by that class as if they re local methods. A DRb client can be as simple as this:

Now that you ve prepared and reviewed the PowerPoint le, it s time to start planning the presentation s visuals with a few sketches.

Only one line is required to retrieve an instance of a class from a remote DRb server. Whereas with XML-RPC you first create a handle to the server, with DRb you create a handle to a class instance. After you use DRbObject.new, remote_object is a handle to the object served by a specific DRb server (in this case, a local server).

Let s look at the server associated with this client:

Now that you ve created the Key Point slides, an effective technique to keep these most important concepts continually fresh during a 45-minute presentation is to duplicate them at the end of each corresponding section. To do that, in Slide Sorter view, hold down the Ctrl key as you click the Key Point slides 1 and 2, and with the two slides selected, press Ctrl+D to duplicate these two slides. Now drag the duplicate Key Point slide 1 directly in front of Key Point slide 2, and then drag the duplicate Key Point slide 2 in front of Key Point slide 3. With these duplicated slides in place, after you present

require 'drb' class OurClass def some_method "Some test text" end end DRb.start_service nil, OurClass.new puts "DRb server running at #{DRb.uri}" trap("INT") { DRb.stop_service } DRb.thread.join

Compares two values Returns the length of a sequence Converts a sequence to a list Returns the maximum of a sequence or set of arguments Returns the minimum of a sequence or set of arguments Lets you iterate over a sequence in reverse Returns a sorted list of the elements of seq Converts a sequence to a tuple

It couldn t be simpler. DRb.start_service associates an instance of OurClass with the DRb server, it prints the URL to the DRb server to the screen, and then starts the DRb server and awaits client connections.

Note You need to change the druby:// URL in the client example to match the URL given in output by

With DRb, data structures work almost seamlessly across the connection. If your remote classes want to return complex hashes, they can, and they ll be represented perfectly on the client. To an extent, using an object over a DRb connection is transparent, and the object will act as if it were local. This is only a simple overview of the basics of DRb. However, in terms of DRb s basic RPC features, this simple server-and-client example demonstrates the core of DRb s feature set, and you can extend it to almost any complexity. If your code is already written using classes, you might be able to drop DRb in within minutes and immediately get your functionality working from afar.

the Explanation and Detail slides for Key Point slide 1, you ll see Key Point slide 1 again to serve as a visual summary of the material before moving on to Key Point slide 2. The same thing will happen after the Key Point slide 2 section, except you ll see the duplicate Key Point slide 2 again before moving directly to Key Point slide 3.

Summary

Now that you re acquainted with sequences, let s move on to character sequences, also known as strings.
