Types ¶

type BoltData ¶

type BoltData interface {
	GetID() uint64
	SetID(id uint64)
}

type Repository ¶

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

func NewRepository ¶

func NewRepository(b *bolt.DB) *Repository

func (*Repository) Add ¶

func (b *Repository) Add(bucketNames []string, data interface{}) (uint64, error)

add adds data to bolt and set new ID which generated by bolt to data. So this method modifies data argument. This method always assign new ID to data, so even if already data have ID other than 0, it will be ignored and overwritten.

func (*Repository) AddIntByString ¶

func (b *Repository) AddIntByString(bucketNames []string, k string, v uint64) error

func (*Repository) AddWithID ¶

func (b *Repository) AddWithID(bucketNames []string, data BoltData) (uint64, error)

addWithID adds data to bolt and set new ID which generated by bolt to data. So this method modifies data argument. This method always assign new ID to data, so even if already data have ID other than 0, it will be ignored and overwritten.
