Talk:Object lifetime

Latest comment: 5 months ago by Stevebroshar in topic Focus

Would it not better to perform some common task (like with points) in the three programming languages to show the difference? --VictorAnyakin 06:56, 14 September 2006 (UTC) .n,n,. —Preceding unsigned comment added by 210.212.103.252 (talk) 18:04, 26 February 2008 (UTC)Reply

Removed alot of nonsense; including the examples. This article is about lifetime which is about _how_ life starts and ends. It is only loosely related to _what happens_ when it starts and ends. If talking about behavior, then lifetime covers all behavior; not just ctor and dtor.

  • Rules for object lifetime vary between languages, in some cases between implementations of a given language. -- so generic
  • lifetime of a particular object may vary from one run of the program to another -- How is that interesting?
  • both for static variables and automatic variables -- so ... variables
  • in general, object lifetime is not tied to the lifetime of any one variable -- huh?
  • particularly those that use garbage collection (GC) – objects are allocated on the heap -- tangent
  • Further, many distinctions are drawn between the steps, and between language-level concepts and implementation-level concepts. -- so generic
  • The terms allocation and deallocation or freeing are also used, by analogy with memory management, though object creation and destruction can involve significantly more than simply memory allocation and deallocation, and allocation/deallocation are more properly considered steps in creation and destruction, respectively. -- huh?
  • This varies by language, and within language varies with the memory allocation of an object; object lifetime may be distinct from variable lifetime. -- Duplicate info
  • efn|There are various subtleties; for example in C++, static local variables are deterministically created when their function is first called, but destruction is non-deterministic. -- don't use efn and way too specific and c++ oriented
