如果__n不为nullptr,说明之前已有同样元素存在。 如果hash表元素是int,那么会生成一个为其特化的hashtable,其hash值不需要计算,而是直接用value % 11得到其__bkt值,进而插入hash表。
Now let’s turn to the hash table implementation (ht.c).Create and destroyAllocating a new hash table is fairly straight-forward. We start with an initial array capacity of 16 (stored in capacity), meaning it can hold up to 8 items before expanding. There are two allocations, one for ...
I just wanted a simple and straightforward hash table implementation that I could drop into my own C-based projects on whatever platform. I haven't implemented one of these before, so it may be super naive, but it does appear to work pretty well. ...
this hash table implementation is currently hardwired to be used with string keys. it would be trivial to support other types too, but the more generic, the more messy the API becomes. see test.c for usage examples. Releases No releases published...
实验2.2 HASH TABLE IMPLEMENTATION 0、概要 这一个部分我们需要结合之前的BufferPoolManager来完善哈希表的增删改查的操作. 初始情况下global depth为0,directory大小为1<<0=1,因此只有一个bucket,此bucket的local depth为0。这时插入键值,取哈希函数中间结果的后0位,得到的directory下标总是为0,所有的元素全进入这个...
// implementation (subclass): staticHashTable*create(intkeyType); virtualvoid*Add(charconst* key,void* value)=0; // Returns the old value if different, otherwise 0 virtualBooleanRemove(charconst* key)=0; virtualvoid*Lookup(charconst* key)const=0; ...
The objects used as keys by aHashtableare required to override theObject.GetHashCodemethod (or theIHashCodeProviderinterface) and theObject.Equalsmethod (or theIComparerinterface). The implementation of both methods and interfaces must handle case sensitivity the same way; otherwise, theHashtablemight...
1.HashTable的数据结构上下文 我们以debug模式运行redis-server的时候,可以看到在redis.c的initServer方法中,初始化了db。 dbnum的值来源于配置:databases,默认为16。 在Redis.h中,对每个数据库实例做了定义: /* Redis database representation. There are multiple databases identified ...
