Talk:Smart pointer

Example
I have included an example in C++ language. Note I was aware of WP:MOS. I thought first person was suitable because the comments behave as a mathematical deduction.

I have tried to make the example independent from whether the approach is intrusive, so it does not depend on the counter being stored into the object, as well as it does not depend on the counter being stored into the smart pointer. For instance, q = obj_1; instead of q = p; will not work in the latter case.

Also, the following will not work with some implementations (as stated by Alexandrescu, Modern C++ Design) so I modified the example for compatibility with the general case. Object* obj_1 = new Object; SmartPointer p= obj_1; SmartPointer q= obj_1;

I would like your opinion about this paper (in Spanish). It contains an analysis of drawbacks which could be useful in the article (sections 3 and 4). However, since I'm one of the authors of that work, I submit it for discussion, per WP:COI. Rjgodoy 23:25, 29 May 2007 (UTC)


 * Um.... i'm going to fix this, no offense. Revert if you want, i won't be back to keep an eye on the page. have you heard of WP:NOTGUIDE - wikipedia is not a tutorial .'. doen't use instructional examples, in general terms. -Oxinabox (talk) 04:33, 1 January 2009 (UTC)

track of the objects that point to them/they point
The wording "[SPs] keep track of the objects that point to them" instead of "[SPs] track of the objects that they point" is intentional. A SP tracks how many objects are actually pointing *it* (because the raw pointer cannot track them by itself) and each SP usually manages only one object. Besides of some quirks, it seems as if the outer objects were pointing to the target object, but they are pointing to the SP. I hope the distinction is clear.

 * In short, the answer to your question is yes, they point to the target object, but they track how many references (to the smart pointer, and indirectly to the target object) are in scope at any given moment. The target object itself is not tracked but managed. Rjgodoy (talk) 02:59, 15 May 2008 (UTC)

Well, yeah. That does make sense. Nice word Rjgodoy!

Øøh, cool!
A large bunch of code, coO O Ool! For nerds like me, that is. However I would wager that not everyone reads C++ fluently. Maybe perhaps instead the general principles could possibly be explained in English? Rursus dixit. ( m bork3 !) 15:57, 14 October 2010 (UTC)

C++ focus in general topic
Is it just me who finds it a little dismaying that a topic on a general issue has such a strong single language focus? DarkPhoenix (talk) 09:24, 8 November 2019 (UTC)
