Contribution to Implementation

CommandHandler class

To kick off the coding of the project, Andy and I started early by planning on the style of parsing user input and command handling. We decided to follow the parsing style similar to the Apache Commons CLI 1.4. We initially tested the Commons CLI library, but it was rather basic, and we rather have our own control over parsing and command handling. Andy was in-charged of the ParserHandler, while I started with CommandHandler and Command classes. With Andy’s parsing technique being refined over the iterations, the CommandHandler had much more reliable parsed data to handle. By separating the parser and command creation, this increases cohesion.

Command classes

Following what I’ve learnt in iP, I applied the same strategy to the Command class structure. This is the cleanest and simplest implementation, inspiration from AB-3. Discussed this implementation with Jonah.

AddCommand class

To re-distribute the workload, I decided to do less on the logic of each command, and decided to help contribute to the AddCommand class, focusing on the validation of the arguments.

Utils class

By focusing more on argument validation, I’ve decided to place the commonly used validation methods into the Utils class. These validation methods are to ensure that argument types are properly enforced, like option validation and option value validation.

Others

Most notably, the DateFormat and Command validation process.

Contributions to UG

Add explanations for the command formats and notation, date format, and the add feature. Was in-charged of the command summary, later edited and refined by Gerard.

Contributions to the DG

Documented the Architecture, and the Command handler and Command Components. Also worked on the AddCommand Implementation. This includes the UML class, object and sequence diagrams.
