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

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.
