这个hash算法的名称叫:BKDR Hash Function This hash function comes from Brian Kernighan and Dennis Ritchie's book "The C Programming Language". It is a simple hash function using a strange set of possible seeds which all constitute a pattern of 31...31...31 etc, it seems to be very simi...
you should consider choosing a more secure hash function when using a GHashTable with keys that originate in untrusted data (such as HTTP requests). Using g_str_hash() in that situation might make your application vulnerable

HashString 项目 2015/01/20 HashString TheHashStringfunction calculates a hash value from a specified string. Syntax int HashString( string input, int multiplier, int maxValue, bool caseSensitive ); Parameters input Specifies the string to be hashed. ...
The function returns a STRING type value, determined by the following conditions: If str is not a STRING, BIGINT, DOUBLE, DECIMAL, or DATETIME type, an error is reported. If the value of str is null, the function returns null. Examples Example 1: To calculate the MD5 hash of the stri...
The RtlHashUnicodeString routine creates a hash value from a given Unicode string and hash algorithm.SyntaxC++ Copy NTSYSAPI NTSTATUS RtlHashUnicodeString( [in] PCUNICODE_STRING String, [in] BOOLEAN CaseInSensitive, [in] ULONG HashAlgorithm, [out] PULONG HashValue ); ...
HotSpot VM里,记录interned string的一个全局表叫做StringTable,它本质上就是个HashSet。这是个纯运行时的结构,而且是惰性(lazy)维护的。注意它只存储对java.lang.String实例的引用,而不存储String对象的内容。 一般我们说一个字符串进入了全局的字符串常量池其实是说在这个StringTable中保存了对它的引用,反之,如果...
function标签,name代表分片算法的名字,算法的名字要和上面的tableRule中的<algorithm>标签相对应。class:指定分片算法实现类。此处需要填写为"jumpstringhash"或者"com.actiontech.dble.route.function.PartitionByJumpConsistentHash"的分区规则,property指定了对应分片算法的参数。不同的算法参数不同。
