Java面试:ConcurrentHashMap 底层原理 ConcurrentHashMap 是线程安全的 Map 容器, JDK8 之前, ConcurrentHashMap 使用 锁分段技术, 将数据分成一段段存储, 每个数据段配置一把锁, 即 segment 类, 这个 类继承 ReentrantLock 来保证线程安全, JKD8 的版本取消 Segment 这个分段锁数据 结构, 底层也是使用 Node...
Templated type-safe hashmap implementation in C using open addressing and linear probing for collision resolution. - DavidLeeds/hashmap
This is a simple C hashmap, using strings for the keys. Originally based on code by Eliot Back athttp://elliottback.com/wp/hashmap-implementation-in-c/Reworked by Pete Warden -http://petewarden.typepad.com/searchbrowser/2010/01/c-hashmap.htmlThis version is now deprecated, since it's ...
Hash table based implementation of the Map interface. This implementation provides all of the optional map operations, and permits null values and the null key. (The HashMap class is roughly equivalent to Hashtable, except that it is unsynchronized and permits nulls.) This class makes no guarant...
