Azzet 是一个简单的 Java 类库，用于从不同的源中加载资源。
示例代码：

BufferedImage img = Assets.load("http://www.google.com/logos/classicplus.png"); // loaded from website
Font fnt = Assets.load("myfont.ttf", new FontInfo(32.0f)); // loaded from classpath
Clip snd = Assets.load("C:\UserData\MyMusic.wav"); // loaded from file-system
BufferedImage gif = Assets.loadFrom("mygif.gif", BufferedImage.class); // you can request the return type
BufferedImage[] animatedGif = Assets.loadFrom("mygif.gif", "db"); // loads from DatabaseSource saved as "db"
Properties props = Assets.loadFrom("app.properties", "tcp"); // loads from TcpSource saved as "tcp"

支持的格式包括：
[color=darkblue]JSON (org.magnos.asset.json.JsonValue)
XML (org.w3c.dom.Document)
PROPERTIES/XML/CONFIG (java.util.Properties, org.magnos.asset.props.Config)
GIF (java.awt.image.BufferedImage[])
PNG/BMP/WBMP/JPEG/JPG (java.awt.image.BufferedImage)
MID/MIDI (javax.sound.midi.Sequence)
WAV/AU/AIFF/SND (javax.sound.sampled.Clip)
TTF (java.awt.Font)
CSV (org.magnos.asset.csv.Table)
CLASS/CLAZZ (java.lang.Class)
JAR (org.magnos.asset.java.Jar)
ZIP (org.magnos.asset.zip.Zip)
GZ (org.magnos.asset.AssetInfo)
DAT (byte[], java.io.InputStream, java.nio.ByteBuffer, java.io.ByteArrayOutputStream)
TXT (java.lang.String, char[], java.nio.CharBuffer, java.lang.StringBuffer, java.lang.StringBuilder)[/color]

支持的数据源：
[color=darkblue]Classpath
File-System
Database
JAR
FTP
HTTP/HTTPS
UDP
TCP
SSL
UDP Multicast[/color]
示例代码：

FutureAssetBundle bundle = new FutureAssetBundle();
bundle.add( Assets.loadFuture("image.gif", BufferedImage.class) );
bundle.add( Assets.loadFuture("sound.wav", Clip.class) );

BufferedImage image = null;
Clip sound = null;

// game loop
while (running) {
   // do stuff
   // this occurs during the loading screen....
   if (bundle.isComplete()) {
       bundle.loaded(); // notify all FutureAsset implementations the asset has been accepted.
       image = bundle.getAsset("image.gif");
       sound = bundle.getAsset("sound.wav");
       // move from loading to play screen
   } else {
       display bundle.percentComplete();     
   }
   // do other stuff
}
