Clarify a concept

[bearsite4]

I remember reading that with parameters are passed:
1. value for primitives, strings and one other
2. reference for objects

So, generally with constructors, you should do an assign if it takes any object parameters to prevent corruption of your object.

Is this correct?

Could you clarify what you are trying to say here.
Maybe then I can help you ...

BobbaFet Everyone has a right to my opinion.

What I meant was that (I'm not entirely sure but I think) when functions/procedures expect a object parameter, that parameter is passed by reference.

So given a class definition:

//class field
private
o1: object;

The constructor should have:

constructor s( o: TObject );
begin
o1.assign( o );
end;

instead of:

o1 := o;
