Pre-compiling a script

[Vinicius Souza]

Im creating a program where I need to execute the same script continuously so I was wondering if I can pre compile it ? My code below
package com.xcreator;

package com.xcreator;

import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;

public class Script
{
	public static void main(String[] args)
	{
		Actor ac = new Actor();
		ac.setX(100);
		ac.setY(200);
		ScriptEngineManager engineMgr = new ScriptEngineManager();

		ScriptEngine engine = engineMgr.getEngineByName("JavaScript");
		engine.put("instance", ac);
		try 
		{
			for (int i = 0; i < 100; i++)
			{
				engine.eval("importPackage(com.xcreator);" + 
							"println(instance.getY());" +
							"instance.setY(instance.getY() + 1);");
			}
		} catch (ScriptException ex) {
			System.out.println(ex.getMessage());
		}
	}
}

Thanks in advance!

You can compile a script at runtime if the ScriptEngine implements the Compilable interface.
If so, you can cast it to Compilable and invoke either of the compile() methods to obtain a CompiledScript instance, which you can then re-use as often as you like.
