Garbage Collection Algorithms For Automatic Dynamic Memory Management - Richard Jones. The last example with circular reference To ensure fast object allocation, short garbage collection pauses, and no memory fragmentation V8 employs a stop- the-world, generational, accurate, garbage collector. This means that V8: stops program execution when . An alternate approach to memory management that is now commonly utilized, especially by most modern object-oriented languages, is automatic management by a program called a garbage collector“ There are various Garbage Collection algorithms and each platform implements its own. Unlike JAVA garbage collection mechanism where the memory for allocated object is automatically reclaimed by system when it goes out of scope, in iPhone framework developer need to take care of releasing the memory for the object. NewLISP also does references passing by packaging variables into contexts. But, to start off with, what is garbage collection? Garbage collection is a system of automatic memory management. I used to read article like the one on C++ User Journal about the “The Rule of Three” or rule of thumb like if you dynamically allocate memory you need the Rule of Three. Creating lots of objects also has the side effect of generating garbage collection. When zombies are enabled, a deallocated object's class is dynamically changed to be _NSZombie, and by default, the memory region is never marked as free, although this can be controlled separately. From a user's perspective, newLISP's memory management works just like garbage collection in other scripting languages: memory gets allocated automatically and unused memory gets recycled. So the garbage collector algorithm already needs to be clever about what it's doing. Dynamic scoping style seems not to be a disadvantage when using the language, as long as you divide your code into context modules. In the latter case, new causes the class' constructor to be called automatically. Fundamentals of OOP and Data Structures in Java - Richard Wiener.
