While working on my jfig parser I was doing some google searching regarding Java enum feature. Came across a tutorial on a technique making clever use of Java enum, and which was dubbed:
template method pattern Here's a code snippet based on something I implemented using this technique per my jfig parser: http://vossnet.org/template_method_pattern-a_code_snippet.rtf (Open in something that handles rtf and will have color syntax source code.) The gist is that this is a very nice way to bind strings to methods that are in themselves associated to enum ordinals. Input a string from somewhere, bind it to its respective enum ordinal, and then execute a method on the enum object in a OOP polymorphic manner. OOP polymorphic method dispatch insures the correct method implementation gets invoked. Would be a great way to roll minimalist command pattern implementations, which are frequently driven by simple command strings. And is just the ticket I need for my parser where will by doing such string binding/execution on a frequent basis. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "The Java Posse" group.
