Examples

The examples are tested with CaesarJ compiler 0.8.5.

Simple examples

Here you can find source code of some examples. These examples are explained in detail in the Programming Guide.

How to run examples?

Unpack example in the Eclipse workspace directory.
Use [File->Import->Existing project into workspace].
Build the project and run the class with main() method.

Large Examples

L2 Interpreter

L2 is a mini object-oriented language. The example demonstrates a modular and extensible implementation of the interpreter for the language in CaesarJ.

You will find several test programs of L2 and its sample extension in /src/l2examples. To test the interpreter you can run the unit tests in /src/test.

Dungeon Game

Dungeon is a middle size case study that demonstrates feature-oriented programming with CaesarJ.

Dungeon is a real-time game written in CaesarJ. The goal of the game is to find the princess in a labirinth of underground rooms. Some of the rooms contain monsters or entrapments. The player can collect various items: weapons, armor, potions and money. Weapons and armor can be configured in the inventory window.

To start the game run the "de.tud.st.dungeon.Run" class. The class shows a dialog which allows you to customize the game. Switch on the desired game features and press "START!!!".

Game controls:

left mouse click on a location or a monster: move to this place or to attack the monster.
right mouse click: enter and leave the inventory window
middle mouse click on a merchant: start trading.
1 : normal battle mode
2 : parry battle mode
3 : agressive battle mode

To run the example you will have to extend the stack of JVM threads. This can be done by adding "-Xss1M" argument in "Run...->Arguments->VM Arguments".

To run the example you also have to install [https://java3d.dev.java.net/ Java 3D]]

Remoting Examples

Remote Pricing

Pricing example with StockBroker residing on remote process. The example demonstrates how we can deploy aspects on the threads of remote process.

To run the example:

Unpack example in the Eclipse workspace directory.
Use [File->Import->Existing project into workspace].
Set CAESAR_HOME variable in Eclipse Ant settings to point to the CaesarJ plugin installation location.
Run build.xml with default target. It will build all sources and prepare some of the classes for remoting.
Refresh project
Run class stockinformationbroker.StockInfoServer to start server process.
Run class client.ClientTest to start client process.

Remote Hierarchies

Hierarchies example with client-server architecture. Data model resides on the server process, while the UI runs on the client side
