Functions

func GetLongID

func GetLongID() (i int64)

func Lock

func Lock(key string)

func NextID

func NextID() int64

func ParseId

func ParseId(id int64) (t time.Time, ts int64, workerId int64, seq int64)

ParseId Func: reverse uid to timestamp, workid, seq

func QuickSort2

func QuickSort2(arrInter interface{}, compare func(x, y uintptr) bool)

只支持指针数组，通过指针侵入数组，但是对于compare里的uintptr要做转换，如下： str := (*string)(unsafe.Pointer(x))

func RLock

func RLock(key string)

func RUnLock

func RUnLock(key string)

func UnLock

func UnLock(key string)
