CMapIterator advances

Hi. Using CMapIterator is a little annoying because of one thing - I always have to rewind before use.


$t    = new CMap(array('1','2','3'));

$k=$t->getIterator();

echo var_export($k->current(),1);

will produce NULL




$t    = new CMap(array('1','2','3'));

$k=$t->getIterator();

$k->rewind();

// now we are ready to go

echo var_export($k->current(),1);

will produce 1 of course. So, u cant work with your iterator since u rewind it first.

Just one change in constructor’d make me more happy:




public function __construct(&$data)

	{

		$this->_d=&$data;

		$this->_keys=array_keys($data);

		$this->rewind(); // we do rewind after all properties are established to find out the current (first element)

	}

tx.

This’d be better:




public function __construct(&$data)

        {

                $this->_d=&$data;

                $this->_keys=array_keys($data);

                $this->_key = current($this->_keys); // we do rewind after all properties are established to find out the current (first element)

        }

You are expected to use the map in the following way:




$map=new CMap(array(1,2,3));

foreach($map as $key=>$value) ...
