Create a Filtextulator

Apply advanced object-oriented language skills Assignment -

Instructions - For this assignment you will create a 'Filtextulator'.

Filtextulator is a new made-up word. It refers to a program that transforms text in weird and wonderful ways, using filters.

You will create a server application that accepts some text and some instructions, alters the text according to the instructions, and returns the result.

You will also create an Android client. This client will accept some text and instructions regarding the filters from the user, ask the server to process the information, and display the result to the user.

A Server Application - Using JEE, build a server application that:

contains at least four text filters (some suggestions are listed below)
can accept a request for, and respond with, a list of available filters
can accept some text, plus a list of filters in a specific order, and respond with the text after those filters have been applied

The server application should include -

unit tests, using mocking where appropriate - each filter should have at least one unit test
some integration tests - some of the tests should test the result of applying multiple filters
JavaDoc

Filter Suggestions -

This is a list of possible text filters you could implement. You are not required to implement these specific ones, however this list should indicate the type and range of filters expected.

change each word to start with uppercase, with remaining letters lowercase
remove all spaces
remove all vowels
apply simple encryption using ROT13 ('a' becomes 'n', 'b' becomes 'o' and so on.
encrypt using the latin alphabet version of Atbash ('a' becomes 'z', 'b' becomes 'y' and so on.
use 'pig latin' (move the first consonant to the end, and add 'ay'. So 'pig' becomes 'igpay' and 'hello' becomes 'ellohay'.
use 'opish' ('op' is added after each consonant. So 'pig' becomes 'popigop' and 'hello' becomes 'hopeloplopo')
reverse each word (So 'pig' becomes 'gip' and 'hello' becomes 'olleh')

A Client Application -

Build an Android application that:

1. requests from the server a list of available filters

2. displays that list to the user

3. allows the user to reorder the list of filters using drag and drop

4. allows the user to turn off one or more of the filters

5. allows the user to type in some text

6. when the user clicks a specific button, the client sends the text plus the list of chosen filters to the server for processing, then displays to the user the altered text returned from the server.

The application should include:

documentation for the user
JavaDoc
error handling: if the server returns an error, or cannot be contacted, the application should detect this and inform the user

Design Guidelines and Suggestions -

Create an interface or an abstract class for use by all filters. Your server code should use these filters by their interface/abstract class type. That way you can later add more filters with minimal change to your server.
Think about design patterns you could use. For example, depending on how you decide to design your filters, the Factory Pattern might be useful.
The body of your requests should be formatted in your choice of either XML or JSON. The format should also be documented.
A servlet or controller should contain as little code as possible. Your filters, and the code to use them, should mostly not be in a servlet, but instead called upon by the servlet.
The list of filters sent to the client should include some sort of description of the filter, for display to the user, as well as some sort of 'short' name, that the server uses to recognise a specific filter.
Think about handling the following sorts of errors in the client: server not reachable, server's response missing expected information, and server responds with error message
Think about handling the following sorts of errors in the server: client requests unknown filter, client sends empty text to be filtered, and client requests no filters

If you haven't created a program of this size before, it can seem a bit daunting. Pick one small part that seems easier than the rest, that will let you see something. Create a program that does this thing, only. Then pick another small feature, and add that. Keep going, and you end up with a full program!

The Assignment will assess competencies for ICTPRG501 Apply advanced object-oriented language skills. If you haven’t created a program of this size before, it can seem a bit daunting. Pick one small part that seems easier than the rest, that will let you see something. Create a program that does this thing, only. Then pick another small feature, and add that. Keep going, and you end up with a full program! For example, you might approach the Android app by first creating an app that shows a screen wth a list. The list might be String resources, and might be a list of fruit, or your favourite movie titles. Try it out, make sure it works as you want. Then you might add a text box where the user can type something. Then add a button. Then add code so that when the user taps the button, a new screen displays the text. Keep going in this way, and eventually you will have an entire app.

Code Design and Quality - Has a coding standard been followed consistently? Are classes divided into logically sensible packages? Are controller methods short? Non-trivial work should be in a separate, potentially reusable class. Is invalid input checked for and handled? Does the design support easy addition of new filters, preferably via polymorphism? Is there evidence of considered use of Design Patterns? Are all Exceptions handled? Unit Testing - Are Unit Tests included? There should be, at minimum, one for each text filter. Is each unit test small, and easy to understand? Has mocking been used appropriately? Is there at least one integration test that tests applying more than one filter? Does each test have either a comment, or suitable name, so it is easy to tell what it is designed to test and what the expected outcome is? Do all tests pass?
