1o Projeto de LP2 (2018)

Our solution

Division of Tasks

Nuno took care of Game (represents each object from the .csv file) and UserInputs (manage user inputs from all the menus) classes. Rui created ReadFromFile (read from file and turn each object into Game) and ManageSearchEngine (sort, filtering, etc). Renderer methods were created by both.

Both worked on all the classes as the project kept improving.

Extras were implemented by both.

• Rui: Show downloaded image to user.

• Nuno: Show help website if user chooses so.

Architecture

When starting the program, values are read from the specified .csv file and values are put into a List. Then the user can simply search a game by ID, or do an advanced search in which Sort and Filtering can be applied.

For this project we created a ReadFromFile class which reads from the specified .csv file and turns each line into a Game object. Each Game object was stored into a HashSet<Game> (both Equals() and GetHashCode from Game class were overriden to compare Game objects by ID, avoiding repeated games). After that, the HashSet values were passed into a List so we could sort it later.

For the sort and filtering, we used lambda expressions on a new list that receives all the values from the original one. After each search or if the user goes back to the previous menu, the filtered list receives the original list values again (resets).

Conclusions

This was a simple project, but it expanded our knowledge as we used a new collection (HashSet) and learned how useful it can be. Same goes to lambda expressions which made it so much easier to do both Sort and Filtering options.

Overall it was fun to do, and we both worked equally hard which helped a lot to finish everything in time.
