Hello Dear Freepascal users, I'm a newbee to object pascal. I did however program in turbo pascal. The past couple of days I learned that there exist a variety of classes/object systems in freepascal. Now, I already figured out that the generic class generators are that what we are looking for, which means that we will be generating classes.
Now, as far as I understand it, these classes are in a sense 'smart
pointers' (yes, I come from a C++ env), and I found some hints at
various places that automatic reference counting should be available in
object pascal. So I tried a little testprogram to see when the objects
instatiated from a class are disposed off. Below is the little program:
{$mode objfpc}
Type
TReferenceCount = Class
Public
nummerke: Integer;
Destructor Destroy;
end;
Destructor TReferenceCount.Destroy;
begin
WriteLn('Deallocation');
end;
var
Test : TReferenceCount;
Pest : TReferenceCount;
begin
Test:=TReferenceCount.Create();
Pest:=Test;
Test.nummerke:=100;
WriteLn('Nummerke in test is ', Test.nummerke);
WriteLn('Nummerke in pest is ', Pest.nummerke);
Pest.nummerke:=200;
WriteLn('Nummerke in test is ', Test.nummerke);
WriteLn('Nummerke in pest is ', Pest.nummerke);
Test:=nil;
Pest:=nil;
end.
So, the question now is where I can find documentation on the reference
counting mechanism in freepascal ?
Any help would be appreciated,
Wkr,
