Description

package test.propertyaccess;

import org.apache.tapestry5.ioc.Registry;
import org.apache.tapestry5.ioc.RegistryBuilder;
import org.apache.tapestry5.ioc.services.ClassPropertyAdapter;
import org.apache.tapestry5.ioc.services.PropertyAccess;
import org.apache.tapestry5.ioc.services.PropertyAdapter;

public class App {

public interface MyBeanInterface

{ int getValue(); }

public interface MyEditableBeanInterface extends MyBeanInterface

{ void setValue(int value); }

public static void main(String[] args)

{ // init RegistryBuilder builder = new RegistryBuilder(); Registry registry = builder.build(); registry.performRegistryStartup(); // get property adapter PropertyAccess propertyAccess = registry.getService(PropertyAccess.class); ClassPropertyAdapter classAdapter = propertyAccess.getAdapter(MyEditableBeanInterface.class); PropertyAdapter propertyAdapter = classAdapter.getPropertyAdapter("value"); // print System.out.println(propertyAdapter.isRead() ? "value is readable" : "value is not readable"); System.out.println(propertyAdapter.isUpdate() ? "value is updateable" : "value is not updateable"); }

}

Output:
value is readable
value is not updateable
Why?
