OMC CORBA-interface for Java

A simple java implementation of OpenModelica's CORBA interface. Java-clients should use this library to communicate with omc.

Common workflow

A common workflow example:

OMCInterface omci = new OMCClient();
//1. connect to server; now omci is usable
omci.connect();

//2. start communication
Result res = omc.sendExpression("model abc Real x=1; end abc;");
System.out.println(res);

//3. disconnect from server;
//omci isn't usable until a call to connect()
omci.disconnect();

Helpers, Converters

We provide converters which makes the creation of an Modelica-expression easier. For example if you want to create a modelica-array from a list:

List<Integer> xs = Arrays.toList(1,2,3,4);
String modelicaArray = ScriptingHelper.asArray(xs);

The helpers avoid common pitfalls like missing ", , {, etc.

Notes

• This implementation is based on OpenModelica’s System Documentation V. 2013-01-28

• omc’s scripting-API is documented at API

• If an omc-instance gets started as subprocess stdin and stdout are redirected into $TMP/omc_home/omc.log.

• Running 1 test in gradle: gradle test --tests <TESTNAME>
