  2. Garbage collection (computer science) - Wikipedia

    en.wikipedia.org/wiki/Garbage_collection...

    Stop-and-copy garbage collection in a Lisp architecture: [1] Memory is divided into working and free memory; new objects are allocated in the former. When it is full (depicted), garbage collection is performed: All data structures still in use are located by pointer tracing and copied into consecutive locations in free memory.

  3. Garbage-first collector - Wikipedia

    en.wikipedia.org/wiki/Garbage-first_collector

    Garbage-first (G1) collector is a server-style garbage collector, targeted for multiprocessors with large memories, that meets a soft real-time goal with high probability, while achieving high-throughput. [2] G1 preferentially collects regions with the least amount of live data, or "garbage first". [3] G1 is the long term replacement of CMS.

  4. Tracing garbage collection - Wikipedia

    en.wikipedia.org/wiki/Tracing_garbage_collection

    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 ...

    en.wikipedia.org/wiki/List_of_programming...

    Objective-C and Objective-C++ support optional reference counting and garbage collection as alternatives to manual memory management (Apple deprecated the garbage collector). PostScript originally required developers to manually reclaim memory using the save and restore operators. PostScript Level 2 introduced a garbage collector, but its usage ...

  6. Manual memory management - Wikipedia

    en.wikipedia.org/wiki/Manual_memory_management

    In computer science, manual memory management refers to the usage of manual instructions by the programmer to identify and deallocate unused objects, or garbage.Up until the mid-1990s, the majority of programming languages used in industry supported manual memory management, though garbage collection has existed since 1959, when it was introduced with Lisp.

  8. Garbage (computer science) - Wikipedia

    en.wikipedia.org/wiki/Garbage_(computer_science)

    Garbage collection uses various algorithms to automatically analyze the state of a program, identify garbage, and deallocate it without intervention by the programmer. Many modern programming languages such as Java and Haskell provide automated garbage collection.

  9. Object lifetime - Wikipedia

    en.wikipedia.org/wiki/Object_lifetime

    With garbage collection, objects may be destroyed when they can no longer be accessed by the program. The garbage-collector calls a finalizer before memory deallocation. Destroying an object will cause any references to the object to become invalid. With manual memory management, any existing reference becomes a dangling reference. With garbage ...
