Types

type Reader

type Reader struct {
	Data []chutils.Row // Data
	// contains filtered or unexported fields
}

Reader struct satisfies chutils.Input. The Data/Validate slices are the same as those returned by the Read method of chutils.Input. This can be useful when one wants to read data, alter it in some way, and then re-read it or write it out.

func NewReader

func NewReader(data []chutils.Row, tableSpec *chutils.TableDef) (ramData *Reader, err error)

NewReader creates a new Reader instance

func (*Reader) Close

func (rdr *Reader) Close() error

func (*Reader) CountLines

func (rdr *Reader) CountLines() (numLines int, err error)

func (*Reader) Read

func (rdr *Reader) Read(nTarget int, validate bool) (data []chutils.Row, valid []chutils.Valid, err error)

Read func

func (*Reader) Reset

func (rdr *Reader) Reset() error

func (*Reader) Seek

func (rdr *Reader) Seek(lineNo int) error

Seek to a specific row. lineNo starts at 1.

func (*Reader) TableSpec

func (rdr *Reader) TableSpec() *chutils.TableDef
