Under tracing garbage collection, the request to allocate a new object can sometimes return quickly and at other times trigger a lengthy garbage collection cycle. Under reference counting, whereas allocation of objects is usually fast, decrementing a reference is nondeterministic, since a reference may reach zero, triggering recursion to ...
Garbage collection may take a significant proportion of a program's total processing time, and affect performance as a result. Resources other than memory, such as network sockets, database handles, windows, file descriptors, and device descriptors, are not typically handled by garbage collection, but rather by other methods (e.g. destructors ...
Garbage collection is performed by copying live objects from one semispace (the from-space) to the other (the to-space), which then becomes the new heap. The entire old heap is then discarded in one piece. It is an improvement on the previous stop-and-copy technique. [citation needed] Cheney's algorithm reclaims items as follows:
Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE. "Say" for EG, used to mean "for example". More obscure clue words of this variety include: "Model" for T, referring to the Model T.
Garbage collection, or waste collection, is part of municipal waste management. Garbage collection may also refer to: Garbage collection (computer science) , in automatic memory management

Weak references may be used by a garbage collector to determine the objects that are almost collectable. Seen both as key-value pairs, the main difference between weak references and an ephemerons is the way the garbage collector treats them. For weak references, the garbage collector always follows the value in the key-value pair.
