Types

type Backend

type Backend struct {

	// contains filtered or unexported fields
}

func New

func New(path string) (*Backend, error)

New returns a new SQLite backend opening a database at the given path. If no database exists a new database is be created. If the schema version of the stored database is different from the one in schema.go, an error is returned.

func (*Backend) Delete

func (b *Backend) Delete(ctx context.Context, segID common.RawBytes) (int, error)

func (*Backend) DeleteWithIntf

func (b *Backend) DeleteWithIntf(ctx context.Context, intf query.IntfSpec) (int, error)

func (*Backend) Get

func (b *Backend) Get(ctx context.Context, params *query.Params) ([]*query.Result, error)

func (*Backend) Insert

func (b *Backend) Insert(ctx context.Context, pseg *seg.PathSegment,
	segTypes []proto.PathSegType) (int, error)

func (*Backend) InsertWithHPCfgIDs

func (b *Backend) InsertWithHPCfgIDs(ctx context.Context, pseg *seg.PathSegment,
	segTypes []proto.PathSegType, hpCfgIDs []*query.HPCfgID) (int, error)
