id_generator

简介

各种id生成整合在此

• 远程生成唯一uid/rid
• 本地生成uid/rid
• 本地生成长guid
• 本地生成当前进程生命周期内的唯一段id

组件接口

id_generator.gs

函数原型	函数作用
void init_uid(map para)	初始化uid生成功能(基于redis)
string new_uid(string type = nil)	生成一个指定类型的uid
int new_uid_as_int(string type = nil)	生成一个指定类型的int型的uid
void init_rid(int unique_id)	初始化rid生成功能
string new_rid()	生成一个rid
int new_rid_as_int()	生成一个int型rid
string new_guid()	生成一个GUID
int new_cookie()	生成当前进程生命周期内的唯一cookie值
string new_cookie_as_string()	生成当前进程生命周期内的唯一string型cookie值
