func (*Data) GetPath

func (d *Data) GetPath() string

GetPath returns the access path for current object from root.

func (*Data) Lookup

func (d *Data) Lookup(path string) *Data

Lookup element in nested data structure by a path description. allows for automatic reference resolution (link processing)

func (*Data) Read

func (d *Data) Read(rdr *bufio.Reader) error

Read data definition from reader and re-built as internal data structure.

func (*Data) Write

func (d *Data) Write(wrt *bufio.Writer) error

Write data structure to stream writer.

type Parameter

type Parameter struct {
	Name  string // name of parameter
	Value string // value of parameter (encoded as string)
}

Parameter type declaration.

func (*Parameter) String

func (p *Parameter) String() string
