	// value of this node in the source.
	KeyLineCol(source io.ReadSeeker) (int, int, string)

	// LiteralValue returns the value of this node.
	LiteralValue() interface{}

	// SliceChild returns the child node at the index specified. If this node is not
	// a slice node, an empty AstNode and false is returned.
	SliceChild(index int) (AstNode, bool)

	// KeyValueMap returns a map of keys and values. If this node is not a mapping
	// node, nil and false are returned.
	KeyValueMap() (map[string]AstNode, bool)

	// Tag returns the struct tag used in the config structure used to unmarshal.
