In computer science, reference counting is a programming technique of storing the number of references, pointers, or handles to a resource, such as an...

Automatic Reference Counting (ARC) is a memory management feature of the Clang compiler providing automatic reference counting for the Objective-C and...

Reference counting garbage collection is where each object has a count of the number of references to it. Garbage is identified by having a reference...

to each element. Counting sometimes involves numbers other than one; for example, when counting money, counting out change, "counting by twos" (2, 4, 6...

and reference counting. Reference counting schemes record the number of references to a given object and collect the object when the reference count becomes...

by either adding the concept of a "weak reference" (a reference that does not participate in reference counting, but is notified when the area it is pointing...

object is handled by requiring each object to destroy itself via reference-counting. Access to an object's interfaces (similar to Type conversion) is...

PHP manage object lifetime by reference counting, which makes it possible to use RAII. Objects that are no longer referenced are immediately destroyed or...

such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 2.7's end-of-life was initially set for...

of Automatic Reference Counting (ARC). Objective-C on iOS 7 running on ARM64 uses 19 bits out of a 64-bit word to store the reference count, as a form of...

network sockets. Several types of smart pointers exist. Some work with reference counting, others by assigning ownership of an object to one pointer. Even though...

The jōyō kanji (常用漢字, Japanese pronunciation: [dʑoːjoːkaꜜɲdʑi], lit. "regular-use kanji") system of representing written Japanese currently consists of...

or reference counting. However, a finalizer may create new references to an object, requiring object resurrection to prevent a dangling reference. Wild...
