[Jython-users] For loops in Jython 2.1

[Anthony S. <A.J...@su...>]

Hi all,

I'm trying to adapt a Java class so that "for" loops run smoothly in  
Jython 2.1, but I'm getting confused.

At the moment I'm overriding __getitem__(int), which the API says I  
shouldn't do, and it's giving a java.lang.IndexOutOfBoundsException  
after looping over the items.

Could someone point me to a simple explanation of what happens when a  
"for" loop is called?
	for a in b:
		...
Which methods are invoked and in which order?  __getitem__(PyObject)?   
__finditem__(...)?

(I think __iter__ is a Python 2.2 innovation, so I guess that's not  
involved in Jython 2.1?)

Thanks!

Anthony
