[Jython-users] Using __class__ for introspection sometimes do not work.

[<ber...@ya...>]

With the java code below, I obtain the list of
available methods of the StringTonenizer class (but
not of mother classes) while I am unable to obtain
them for my own Enum class.
Is there somebody able to explain me this difference
and where it is documented (sorry if it is but I
didn't find it) ?

Here is the jython console where I try to introspect
my Enum class (made for demonstration purpose).

Jython 2.0 on java1.3.0 (JIT: null)

>>> dir(enum.__class__)
[]

>>> dir(tokenizer.__class__)
['countTokens', 'hasMoreTokens', 'nextToken']

>>> a = enum.nextElement()
>>> a
'one'

>>> a = enum.nextElement()
>>> a
'two'

>>> a = tokenizer.nextElement()
>>> a
'This'

>>> a = tokenizer.nextElement()
>>> a
'is'

>>> 

And here is the java code.

package trybox;

import org.python.core.*;
import org.python.util.InteractiveConsole;

import java.util.Enumeration;
import java.util.StringTokenizer;

public class TryJython
{

  public TryJython()
  {
  }
  public static void main(String[] args)
  {
    TryJython tryJython = new TryJython();
    tryJython.doIt();
  }

  void doIt()
  {
    Enumeration enum = new Enum();
    Enumeration tokenizer = new StringTokenizer("This
is a test");
    InteractiveConsole console = new
InteractiveConsole();

    console.set("enum", enum);
    console.set("tokenizer", tokenizer);
    console.interact();
  }

  public class Enum implements Enumeration
  {
    String [] values = {"one", "two", "tree", "four",
"five"};
    int index = 0;
    public boolean hasMoreElements()
    {
      return (index < values.length);
    }

    public Object nextElement()
    {
      return values[index++];
    }
  }
}

TIA.

Bertrand.
