Re: [Php-java-bridge-users] How to wrap two PHP objects as java closures, and in Java call a metho

In pseudo code (please see the JSR 223 API for details):

String pA = "class A{function testA($b){echo $b->testB();}}\n"
String pB = "class B{function testB(){echo 'hello world';}}\n"
String test = "<?php "+pA+Pb+" $thiz=java_context()->getAttribute("thiz"); $thiz->call(java_closure(new A()), java_closure(new B()); ?>
 

public void doWork (){
  scriptEngine = new ScriptEngineManager().getEngineByName("php-invocable");
  scriptEngine.put("thiz", this);
  scriptEngine.eval(test);
  ((Closeable)scriptEngine).close();
}
static interface IA { public void testA(IB cc1); }
static interface IB { public void testB(); }
public void call(Object $ccA, Object $ccB) {
  IA ccA = scriptEngine.getInterface($ccA, IA);
  IB ccB = scriptEngine.getInterface($ccB, IB);
  ccA.testA(ccB);
}

Yes, the type is determined lazily. Why is that a problem?

I think this is a misunderstanding. If you don't specify the type, either via getInterface() (see above) or by calling java_closure() with three arguments, the generated procedure is generic, i.e. you cannot call the procedure "testA" on it.
