Using or not using 'assign' and 'assignref'

[Richard]

In J1.5 examples and books, assign() and assignref() are used to pass data from a view into the layout.
I noticed that these seem to be replaced in J1.6 and above by just adding the data to the view object.
Are assign and assignref needed any more and if so, under what circumstances should I use them?

[Hannes Papenberg]

assign() and assignRef() are not needed anymore, since Joomla 1.6/2.5
requires at least PHP 5.2, which has far better memory management, which
is the main reason why those two methods were introduced. Those two
methods are assigning the variables by reference and not by value. PHP4
by default used assign by value, while PHP5 (when using objects) uses
assign by reference.

Bottom line: You don't need assign() and assignRef() anymore.

If anyone's bored, I think a patch that gets rid of all calls to assign() and assignRef() would be awesome. They're not gonna be around forever and than we don't have to worry about them down the road.

Just use $this->variable = $something; in your view.html.php and it will be available in the layout.
Cheers,

How to we pass vars to the display then? I can't seem to get default.php to display mine. The print_r inside of the view prints the data just fine. O.O

Just wondering, all core view classes ('view.html.php') in CMS 2.5 have these variables ($data, $item) protected and thus cannot be set directly from controller.

That's what Rouven was speaking about? To change to

View:

class HelloworldViewHello

{

  public $data;

  // ...

}

Controller:

$view->data = $data;

?
