My code base is different from yours, as the provided
zips to you are made
manually (sigh)
by removing code
bits from my own repository.
•
First of all – my code base is divided into
projects
–
Core
•
Is basically what you got in the first TDD Iter
–
UI
•
Is basically what you got in the MiniDraw Iter
–
Domain
•
My own alpha, beta, …, phi stone solutions
–
Solution
•
Server side full implementation

You get my code, right?
–
But you should not get
my solution code!
–
(You can ‘decompile’
a java .class file into something resembling the original source
code!)
•
And you do not, because
–
Client only depends upon ‘core’
•
Resulting JAR file only contains interfaces
and ClientProxy implementations
–
‘PhiStone’ code only on server…

The HotStone uses the FRDS.Broker library
–
Configured with the URITunnel Client- and
ServerRequestHandler
–
Which is super, because I can configure
extra paths
•
Like the landing page

And allows me to respond to POST requests!

Body ‘variant=alpha’

Lobby will create the game, and
associate its ‘id’ with it.

•
Your servers only handle a single game
–
Game’s objectId does not matter
•
I have a GameInvoker which of course must use a Name
Service to fetch the right game to use
–
The ‘lobby’ maintains the mapping (id, game object)

Configure UI with normal MiniDraw tool
–
But embed it in an Adapter
•
Adapter: Adapt from one interface to another
•
This Adapter is a Window Driver Pattern

Software Engineering and Architecture HotStone + My own Solution
HotStone Primary goal Make a good and exiting learning experience in SWEA Secondary goal To create a real game server, allowing students to play CS@AU Henrik B rbak Christensen 2
Gradle Projects My code base is different from yours, as the provided zips to you are made manually (sigh) by removing code bits from my own repository. First of all my code base is divided into projects Core Is basically what you got in the first TDD Iter UI Is basically what you got in the MiniDraw Iter Domain My own alpha, beta, , phi stone solutions Solution Server side full implementation CS@AU Henrik B rbak Christensen 3
The client subproject You get my code, right? But you should not get my solution code! (You can decompile a java .class file into something resembling the original source code!) And you do not, because Client only depends upon core Resulting JAR file only contains interfaces and ClientProxy implementations PhiStone code only on server CS@AU Henrik B rbak Christensen 4
Handling Multiple Games LandingPages Lobby and objectId
Broker Using URL Tunnel The HotStone uses the FRDS.Broker library Configured with the URITunnel Client- and ServerRequestHandler Which is super, because I can configure extra paths Like the landing page CS@AU Henrik B rbak Christensen 6
Broker and HTTP And allows me to respond to POST requests! POST on /newgame Body variant=alpha Lobby will create the game, and associate its id with it. CS@AU Henrik B rbak Christensen 7
GameId Your servers only handle a single game Game s objectId does not matter I have a GameInvoker which of course must use a Name Service to fetch the right game to use The lobby maintains the mapping (id, game object) CS@AU Henrik B rbak Christensen 8
