[2] Perl uses a simple but efficient reference-based garbage collection that will leak on cycles [16] (though Perl 6/Parrot will use garbage collection [17]). 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. Memory Management: Algorithms and Implementation in C/C++ presents several concrete implementation of garbage collection and explicit memory management algorithms. As I discussed in my last post on Memory Allocation dynamic memory is hard to manage One of the duty of a GC system is to automate this process by tracking down (using various algorithms) such objects and reclaim the memory used by them automatically. You probably heard, read or even learned that Flex was managing the memory automatically for you, does it mean you don't have any responsibility regarding memory management in Flex? Garbage Collection: Algorithms for Automatic Dynamic Memory Management by Richard Jones and Rafael Lins describes the most common algorithms for garbage collection in use. Perl [1] is a general-purpose dynamic programming language supporting multiple programming paradigms (procedural, object-oriented, and functional styles), automatic memory management, built-in support for text processing, and a large collection of third-party modules. JavaScript is a garbage collected language, which means developers generally don't have to worry about memory management, unlike lower level programming languages. There is a delete operator in Flex, but it's only for freeing dynamic properties, not for deleting objects. Garbage Collection does exactly what it's more fancier name “Automatic dynamic memory management” suggests. Memory management in Flex using garbage collection, responsibilities it puts on developers, classical causes of memory leaks and good practices to avoid them. Automatic memory management enables increased The main problem for most dynamic memory allocation algorithms is to avoid fragmentation (see below), while keeping both allocation and deallocation efficient.
