\chapter{External packages}

Some external packages that are not part of the Java Standard Development Kit
were used in this project.

\section{StretchIcon}

StretchIcon enabled the resize of the Room illustration according to the
window's size in the rich Swing GUI, keeping a correct ratio.


\section{Guava}

Guava, from Google, contains several collections, caching, primitives support,
concurrency, annotations and string processing utilities.


\section{Lombok}

Lombok helped avoiding writing dozens of getters and setters by replacing them
with shorter annotations.


\section{Intrinsic Map}

As Items were already containing there names in a field, HashMap<String, Item>
were redundant. IntrinsicMap<Item> and the Mappable interface were created to
avoid this redundance.


\section{Google Web Toolkit}

The Google Web Toolkit was used to create the web version of the game.
It permitted the compilation of Java sources to Javascript code executable
directly inside a web browser, without requiring the Java Virtual Machine.


\section{JSON Simple}

JSON Simple was used to implement the save and load functionalities by enabling
the serialisation of the game datas into JSON Objects.

\subsection{rejava.io}

As some packages required by JSON Simple were not compatible with GWT,
the standard Java StringReader and StringWriter classes were partially
rewritten.
