current()	Returns the current array element.	CMapIterator
key()	Returns the key of the current array element.	CMapIterator
next()	Moves the internal pointer to the next array element.	CMapIterator
rewind()	Rewinds internal array pointer.	CMapIterator
valid()	Returns whether there is an element at current position.	CMapIterator

__construct() method

public void __construct(array &$data)
$data	array	the data to be iterated through

Source Code: framework/collections/CMapIterator.php#40 (show)


public function __construct(&$data)
{
    $this->_d=&$data;
    $this->_keys=array_keys($data);
}

Constructor.

current() method

public function current()
{
    return $this->_d[$this->_key];
}

Returns the current array element. This method is required by the interface Iterator.

public function key()
{
    return $this->_key;
}

Returns the key of the current array element. This method is required by the interface Iterator.

next() method

public void next()

Source Code: framework/collections/CMapIterator.php#79 (show)


public function next()
{
    $this->_key=next($this->_keys);
}

Moves the internal pointer to the next array element. This method is required by the interface Iterator.

rewind() method

public void rewind()

Source Code: framework/collections/CMapIterator.php#50 (show)


public function rewind()
{
    $this->_key=reset($this->_keys);
}

valid() method

public boolean valid()
{return}	boolean

Source Code: framework/collections/CMapIterator.php#89 (show)


public function valid()
{
    return $this->_key!==false;
}
