func (d *DB) Open(name string, reader io.Reader) (*Table, error)

type FileHeader

type FileHeader struct {
	Version              string
	RecordCount          uint32
	FieldCount           uint32

type Table

type Table struct {
	DB          *DB
	Name        string
	Header      FileHeader
	Definition  *dbd.Definition
	Layout      *dbd.Layout
	Records     []byte
	StringBlock []byte
}

func (*Table) Append

func (t *Table) Append(recordSlice interface{}) error

func (*Table) ID

func (t *Table) ID(id int, ent interface{}) error

func (*Table) Index

func (t *Table) Index(i int, ent interface{}) error

func (*Table) Len

func (t *Table) Len() int

func (*Table) Range

func (t *Table) Range(handler interface{}) error

func (*Table) SizeCount

func (t *Table) SizeCount(v vsn.Build) (int, int, error)

Returns the size of this record layout in bytes This is because the size of fields has been known to change from version to version, for instance when localized strings add more locales.

func (*Table) StringRef

func (t *Table) StringRef(i int) (string, error)
