\chapter{Work progression}
\section{Zuul bad}
\section{Zuul better v1}
\subsection{printLocationInfo}
This code duplication has been previously avoided with the printRoomInfo()
method.
It has been renamed to printLocationInfo(), as part of the commit e52a34789, to
match the exercise.
\subsection{getExit}
The exit attributes have been made private and a getter was added in commit
53c427ff3. A switch statement has been used instead of multiple if statements.
\subsection{getExitString}
This method has been added as part of commit ca65af2e2.
\subsection{HashMap, setExit}
Room exits are now stored in an HashMap since commit c9d890b9b. The setExits()
method has been replaced by setExit() which takes advantages of the HashMap.
\subsection{Vertical direction}
In commit 4145a5e8c, the getExitString() method has been modified to be able to
print the availability of the new exits, used in the stairwell at wing 3. Due
to the architecture of these rooms, the side exits that were previously settled
to link them have been kept.
\subsection{keySet ?}
The keySet() method of the class HashMap returns a Set of the keys contained in
the map.
\subsection{getExitString ?}
The getExitString() method returns a String listing the room's exits.
To achieve that, it iterates through the exits Map's keys, that is a Set of
Strings, appending each one to the String that it returns.
\subsection{getLongDescription}
The Room class now uses the previously explained getExitString() method and
includes the getLongDescription() method that returns the full description of
the room since commit e510b08d0.
