## requirements / building

NetUtil requires Java 1.4+. NetUtil has also been successfuly running on Android. It uses sbt 0.13 for building. You can use the included sbt shell script if you do not want to install sbt.

To compile sbt compile, to generate a jar sbt package.

To use NetUtil in your project, you can link to the following Maven artifact:

GroupId: de.sciss
ArtifactId: netutil
Version: 1.0.0

Documentation comes in the form of JavaDoc. The generate the docs, run sbt doc. The resulting file is in target/api/index.html.

You can run some demos using sbt. First run ./sbt. At the prompt:

> run

This will print to available options. E.g.

> run --testPingPong

• Illposed JavaOSC – another OSC library for Java
• oscP5 – OSC library for Processing
• flosc – OSC library (written in Java) for bridging OSC clients and Macromedia Flash
• jmDNS – automatic service discovery library for Java.

Here is some sporadic list of projects which seem to use NetUtil. if you want to have your project added here, send me the links:

• Androidome – android-based emulator for the monome music making device
• jReality
• OscVstBridge – VST plug-in
• Frozen Bubble OSCified
• DiABlu – Scout and LegOSC
• AMICO
• Protocoder

## to-do / known issues

• add special client and server listeners so one can detect channels/connections opening and closing
• add helper classes (multi-server wrapper, message deferrer)
