New Comment:
I got expected result with "this->rewind()" in constructor.
class pi extends ParentIterator
{
public function __construct($iterator)
{
parent::__construct($iterator);
$this->rewind();
}
}

It is a gross misunderstanding.

Description:
------------
ParentIterator that only shows those elements which have children.
But I can't get the expected result without rewind() in starting an
iteration.
Reproduce code:
---------------
$target = array(
'foo' => array(1,2,3),
'bar' => array(11,12,13),
'baz'
);
$rai = new RecursiveArrayIterator($target);
$pi = new ParentIterator($rai);
//$pi->rewind();
while ($pi->valid()) {
var_dump($pi->current());
$pi->next();
}
Expected result:
----------------
array(5) {
[0]=>
int(1)
[1]=>
int(2)
[2]=>
int(3)
}
array(5) {
[0]=>
int(11)
[1]=>
int(12)
[2]=>
int(13)
}
Actual result:
--------------
// no output
