rythm engine in parallel processing Issue

Question

As per javadoc, RythmEngine class is not thread safe I.e. each time I have to build a new class which looks like an overhead. What is the best way to use rythm engine in multi threaded envioronment.

Below sample code is for illustration.

import java.io.File;
import java.util.Map;
import org.rythmengine.RythmEngine;

public class RythmEngineUtil {
    static RythmEngine engine;
    static {
        Map<String, Object> conf;// = configure the object
        engine = new RythmEngine(conf);
    }

    public static String render(File file, Map<String,Object> param){
        return engine.render(file, param);
    }
}

Answer 1

If you construct and init the engine when you app bootstrap, then that instance should be safely used in a multi-threaded environment
