[Jython-users] Not-so-stupid question

[Steve C. <St...@ig...>]

All right, here is a distillation of what I thought was a stupid newbie
question last night, but now I'm genuinely puzzled:

>>> from java.util import Hashtable
>>> h=3DHashtable()
>>> h
{}
>>> h.put("2","3")
>>> h.put("1","2")
>>> h
{2=3D3, 1=3D2}
>>> e=3Dh.elements()
>>> e
java.util.Hashtable$Enumerator@5b5427
>>> e.hasNextElement()
Traceback (innermost last):
  File "<console>", line 1, in ?
AttributeError: hasNextElement
>>> e.hasNext()
1
>>> e.nextElement()
'3'
>>> e.nextElement()
'2'
>>>

h.elements returns a java.util.Enumeration
That interface has hasNextElement() and nextElement() methods.  It does
not have a hasNext() method. Yet under jython, hasNextElement() is not
recognized while hasNext() is recognized.

What is going on here?
