Re: [Php-java-bridge-users] How to wrap two PHP objects as javaclosures, and in Java call a method on the first closure with the secondclosure as parameter?

[<php...@li...>]

Hi Juergen,

I really don't understand the problem. I have posted a test case which does what you want.

I do understand that you don't have the information to resolve the type, so that you must call the methods through the reflection API.

But I don't understand why you insist using your own test case, which cannot work, because you confuse the proxy with the invocation handler.

-------------------------------------
package test;

import java.io.ByteArrayOutputStream;
import java.io.Closeable;
import java.io.OutputStreamWriter;

import javax.script.Invocable;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;

public class TestGetInterface {

    /**
     * @param args
     */
    public static void main(String[] args) throws Throwable {
        //System.setProperty("php.java.bridge.default_log_file", "");
        //System.setProperty("php.java.bridge.default_log_level", "3");
        new TestGetInterface().doWork();

    }

    private ScriptEngine scriptEngine;

    String classA = "class A{function toString(){return '::A';} function invokeA($b){java('java.lang.reflect.Proxy')->getInvocationHandler($b)->invoke($b, "invokeB", array());}}\n";
    String classB = "class B{function toString(){return '::B';} function invokeB(){echo '::B';}}\n";
    String test = "<?php "+classA+classB+" $thiz=java_context()->getAttribute('thiz');\n$thiz->call(java_closure(new A()), java_closure(new B())); ?>";
   
    private void doWork() throws Throwable {
        scriptEngine = new ScriptEngineManager().getEngineByName("php-invocable");
        scriptEngine.put("thiz", this);
        ByteArrayOutputStream out;
        OutputStreamWriter writer;
        scriptEngine.getContext().setWriter(writer = new OutputStreamWriter(out = new ByteArrayOutputStream()));
        scriptEngine.eval(test);
        ((Closeable)scriptEngine).close();

        writer.close();
        if(!"::B".equals(out.toString())) {
            System.err.println("test failed");
            System.exit(1);
        }
        System.out.println("test okay");
        System.exit(0);
    }

    interface IA { public void invokeA(IB ccb); };
    interface IB { public void invokeB(); };
   
    public void call(Object $cca, Object $ccb) throws Throwable {
((php.java.bridge.PhpProcedure)java.lang.reflect.Proxy.getInvocationHandler($cca)).invoke($cca, "invokeA", new Object[]{$ccb});
    }
}

> So, what did you mean with "use the same procedure as above"?

Use the Java reflection API. The above example shows how to do this in PHP and in Java.
