I am trying to understand how the joomla framework works, i see an heavy usage of " :: " in its code, here an example:

function edit ()
{
JRequest::setVar('view, 'single');
$this ->display();
}


from my really basic php understanding in the function edit i call a function setVar() and i pass the paramter 'view' and 'single' in it then the output ($this) is passed to the display() function.

My question is what does :: means? an more precisely referring to the example: JRequest::setVar('view, 'single'); how do you read it and how do you manage it?

Cheers, Nick

I think si related to class and methods,

JRequest Class have a method called setVar, right? if this is correct sorry for posting the question, i just haven't started yet classes and methods...;-)
