Functions

func ByteIndexIsOne

func ByteIndexIsOne(a byte, index int) bool

判断一个byte的指定位置是否为1,顺序为从高位到低位下标分别为0->7

func ByteReverse

func ByteReverse(b byte) byte

func GetBit

func GetBit(s []uint8, index int) (r bool)

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>以下函数为测试，封装好类型的在上面<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 从第0位开始判断

Types

type BitMap

type BitMap struct {
	// contains filtered or unexported fields
}

func NewBitMapFromBase64String

func NewBitMapFromBase64String(s string) (*BitMap, error)

func NewBitMapFromString

func NewBitMapFromString(s string) *BitMap

从string加载

func (*BitMap) Base64String

func (b *BitMap) Base64String() string

base64转化为string

func (*BitMap) CancelBit

func (b *BitMap) CancelBit(index int)

设置指定位置为0

func (*BitMap) Count

func (b *BitMap) Count() uint64

func (*BitMap) IsBit

func (b *BitMap) IsBit(index int) (r bool)

判断指定位置是否为1

func (*BitMap) Length

func (b *BitMap) Length() int

获取当前位数长度

func (*BitMap) Reset

func (b *BitMap) Reset()

func (*BitMap) SetBit

func (b *BitMap) SetBit(index int)

设置指定位置为1

func (*BitMap) String

func (b *BitMap) String() string

转 string
