Re: calling methods that take an array or list of interfaces

Here is an example of a method accepting an interface, and the groovy
script which uses the method successfully (even with beta 7! ;-).

Here is the groovy script (swap Vector for List,ArrayList and also works
grand):
-----------------
java.util.Vector bars = new java.util.Vector();
for(i in 1..10) {
  bars.add(new Bar());
}

foo = new Foo();

foo.doSomething(bars.toArray(new IBar[0]));
-----------------
Here are the corresponding java classes:
-----------------
public interface IBar{
    public void doit();
}
-----------------
public class Bar implements IBar, java.io.Serializable {
        public void doit() {
                System.out.println("this is Bar.doit()");
        }
}
-----------------
public class Foo{
    public void doSomething(IBar[] bars){
       for(int i=0;i<bars.length;i++){
          bars[i].doit();
       }
    }
}
-----------------

Robert.
