Hi Tom,

This syntax is borrowed from C++ (or Java) and is a way to access methods
of classes which have no instance. This is also called a static method.
So if you have
class myclass
{
function myfunction()
{
...
}
}
you can access this function via "myclass::myfunction()", even if there is
no object instantiated. "parent" is a reserved word to access functions of
the superclass.
(I hope I got everything right ;-)
Regards
Alex
