Types

type ErrColIndexOutOfBounds

type ErrColIndexOutOfBounds struct {
	For   string
	Index int
}

func (ErrColIndexOutOfBounds) Error

func (e ErrColIndexOutOfBounds) Error() string

type ErrInvalidID

type ErrInvalidID struct {
	Row int
}

func (ErrInvalidID) Error

func (e ErrInvalidID) Error() string

type Ingester

type Ingester struct {
	ls.Ingester
	ColumnNames []string
}

Ingester is a wrapper for the ls/Ingester struct

func (Ingester) Ingest

func (ingester Ingester) Ingest(context *ls.Context, data []string, ID string) (graph.Node, error)

Ingest a row of CSV data. The `data` slice is a row of data. The ID is the assigned identifier for the resulting object. ID is empty, IDs are assigned based on schema-dictated identifiers.

type TermSpec

type TermSpec struct {
	// The term
	Term string `json:"term"`
	// If nonempty, this template is used to build the term contents
	// with {{.term}}, and {{.row}} in template context. {{.term}} gives
	// the Term, and {{.row}} gives the cells of the current row
	TermTemplate string `json:"template"`
	// Is property an array
	Array bool `json:"array"`
	// Array separator character
	ArraySeparator string `json:"separator"`
