  2. Weak reference - Wikipedia

    en.wikipedia.org/wiki/Weak_reference

    In computer programming, a weak reference is a reference that does not protect the referenced object from collection by a garbage collector, unlike a strong reference.An object referenced only by weak references – meaning "every chain of references that reaches the object includes at least one weak reference as a link" – is considered weakly reachable, and can be treated as unreachable and ...

  3. Associative array - Wikipedia

    en.wikipedia.org/wiki/Associative_array

    In computer science, an associative array, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with finite domain. [1] It supports 'lookup', 'remove', and 'insert ...

  4. Hash table - Wikipedia

    en.wikipedia.org/wiki/Hash_table

    A map implemented by a hash table is called a hash map. Most hash table designs employ an imperfect hash function . Hash collisions , where the hash function generates the same index for more than one key, therefore typically must be accommodated in some way.

  6. Go (programming language) - Wikipedia

    en.wikipedia.org/wiki/Go_(programming_language)

    For a pair of types K, V, the type map[K]V is the type mapping type-K keys to type-V values, though Go Programming Language specification does not give any performance guarantees or implementation requirements for map types. Hash tables are built into the language, with special syntax and built-in functions.

  7. Priority queue - Wikipedia

    en.wikipedia.org/wiki/Priority_queue

    The nodes of the skip list consists of a unique key, a priority, an array of pointers, for each level, to the next nodes and a delete mark. The delete mark marks if the node is about to be deleted by a process. This ensures that other processes can react to the deletion appropriately. insert(e): First, a new node with a key and a priority is ...

  8. Template:Table - Wikipedia

    en.wikipedia.org/wiki/Template:Table

    inner or innercollapse: Uses the mw-collapsible innercollapse classes to make the table collapsible, but only collapse if the table is within a larger table with the outercollapse class. outer or outercollapse: Uses the outercollapse class to collapse any smaller tables within the table it that use the innercollapse class. Can be combined with ...

  9. Virtual method table - Wikipedia

    en.wikipedia.org/wiki/Virtual_method_table

    An object's virtual method table will contain the addresses of the object's dynamically bound methods. Method calls are performed by fetching the method's address from the object's virtual method table. The virtual method table is the same for all objects belonging to the same class, and is therefore typically shared between them.
