Functions

func CalculatePages

func CalculatePages(total, pageSize int64) [][]int64

CalculatePages 计算页面，获取带有起始值的页面的数组 @return 返回一个二维数组， 第一维是多少页，第二维是每页[]int64{start, end} e,g: 假设11个数的列表，分页pageSize是5，那么返回的是：

[]int64{
   []int64{0, 5},
   []int64{5, 10},
   []int64{10, 11},
}

func GetStartEndPosition

func GetStartEndPosition(page, pageSize, total int64) (int64, int64)

GetStartEndPosition 如果是按列表slice进行翻页的话， 计算slice的起始index

func NewLimitClause

func NewLimitClause(listParam *protobuf.ListParam) string

NewLimitClause 从protobuf.ListParam生成limit语句

Types

type Pagination

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

func New

func New(page, pageSize int64, args ...int64) *Pagination

New pagination args[0] is default page size

func (*Pagination) GetLimitClause

func (p *Pagination) GetLimitClause() string

GetLimitClause 获取limit sql子句

func (*Pagination) GetLimitValues

func (p *Pagination) GetLimitValues() (int64, int64)

func (*Pagination) Paging

func (p *Pagination) Paging(data interface{}) (int64, []interface{})

Paging 分页 @return total @return []interface{} 分页后的数据
