A bug with RecursiveIteratorIterator?

[Chris <listschris@xxxxxxxxxxxxxxx>]

I'm trying to extend the RecursiveIteratorIterator class, to limit which 
children it recurses through.

The documentation here:

http://www.php.net/~helly/php/ext/spl/classRecursiveIteratorIterator.html

says that there is a ahapublic method callHasChildren(), which I figured 
was a good place to start. It seemed like it made sense, except for the 
fact that that callHasChildren() does not exist. Overloading the 
function does nothing, and instantiating my extended object, then 
manually calling callHasChildren() results in a method not found error.

Call to undefined method RecursiveIteratorIterator::callhaschildren()

I'm including my complete extension class below

Thanks,
Chris

class CPage_TreeMenuIterator extends RecursiveIteratorIterator
{
	function __construct(CPage_Node $it)
	{
		parent::__construct($it,RIT_SELF_FIRST);
	}
	function callHasChildren()
	{
		echo "CPage_TreeMenuIterator::callHasChildren();<br />\n";
		return parent::callHasChildren();
	}
}
