What does this prototype mean?

[JRevor]

I want to overload the operator = (assignment). The header/prototype the overloading function is supposed to look like this (according to wikipedia)

Type1& operator= (const Type2& b);

What does 1&, and 2& mean?
Is that meant to be used like this?

class Object
{
   //... stuff ...
   Object1& operator= ( Object2&v);
   //... stuff ...
}
//Code

Object1& Object::operator = (Object 2&v) 
{
   //...code...
} 

EDIT : The code above seems not to work. What should i do?

What does 1&, and 2& mean?

It doesn't mean anything. It's not 'Object 2&', it's 'Object2 &'. A reference to an Object2.
