You are not forced to reset the engine. Look at the sample code below:
...
// Create engine for the very first time and reset it
Rete engine = new Rete();
engine.reset(); // One-time reset
...
// Run engine
EngineRunner runner = new EngineRunner(engine);
runner.start();
...
// Halt engine. This will make runUntilHalt() return.
engine.halt();
/**
* EngineRunner thread
*/
public class EngineRunner extends Thread {
private Rete m_engine;
public EngineRunner(Rete engine) {
m_engine = engine;
}
public void run() {
try {
m_engine.runUntilHalt();
} catch (JessException ex) {
...
}
}
}
You can stop the engine and recreate/start the EngineRunner thread as often as needed
without resetting the engine.
