Interpreter Pattern - Directory of sites

Introduction

This page provides a directory of sites that can be used as reference to learn about the Interpreter Design Pattern that is used in Object Oriented Programming.

Directory of sites

Interpreter Pattern (Wikipedia)

  http://en.wikipedia.org/wiki/Interpreter_pattern

Wikipedia page is the first place one would go to get an introduction about a new topic. The page provides a good introduction to Interpreter Pattern and explains where it can be used. The page also gives a few common examples where the pattern is used, and also gives a programming example by explaining how Reverse Polish Notation can be implemented using Java.

Drawbacks

Although the page provides a good introduction to the Interpreter, it is by no means comprehensive. It does not discuss the advantages and disadvantages of the pattern, nor does it compare it with other patterns.

Interpreter (vincehuston.org)

http://www.vincehuston.org/dp/interpreter.html

This website describes the interpreter pattern in simple terms with a real world example. It begins with a two step approach to be followed in order to identify the need for and to implement an interpreter pattern in any problem.Following this is a real world example of the interpreter pattern where it is compared with Musicians represent the musical notation on a staff. The site also provide a checklist that consists of a few simple rules that begin with identifying the need for an interpreter pattern for a given problem and then specify the key steps involved in it’s implementation.

Drawbacks

The example code that is provided attempts to contrast the interpreter pattern design with an older pattern, but it’s not straightforward which makes it difficult to understand the differences between the two approaches.

Interpreter Design Pattern (CodeProject)

http://www.codeproject.com/Articles/186183/Interpreter-Design-Pattern

This website provides more information on how to build expression trees and parse them using the Depth First Search Pattern.

Interpreter(Silversoft.net)

http://www.silversoft.net/docs/dp/hires/pat5cfso.htm

This website is one of the most comprehensive references for the interpreter pattern. It provides detailed information about the classes and all the collaborators in the pattern. It also lists out the advantages of using this pattern and also some of the issues one may face when using this pattern.There are two example programs, that are clearly explained in full detail.

Drawbacks

The order in which the examples appear can discourage further reading since, the simpler C++ code appears after the slightly complicated example in SmallTalk (which is lesser known when compared to C++)
