Function ParseJSON

pkg/util/json/json.go:664–685

ParseJSON takes a string of JSON and returns a JSON value.

(s string)

// ParseJSON takes a string of JSON and returns a JSON value.
func ParseJSON(s string) (JSON, error) {
	// This goes in two phases - first it parses the string into raw interface{}s
	// using the Go encoding/json package, then it transforms that into a JSON.
	// This could be faster if we wrote a parser to go directly into the JSON.
	var result interface{}
	decoder := json.NewDecoder(strings.NewReader(s))
	// We want arbitrary size/precision decimals, so we call UseNumber() to tell
	// the decoder to decode numbers into strings instead of float64s (which we
	// later parse using apd).
	decoder.UseNumber()
	err := decoder.Decode(&result)
	if err != nil {
		err = errors.Handled(err)
		err = errors.Wrap(err, "unable to decode JSON")
		err = pgerror.WithCandidateCode(err, pgcode.InvalidTextRepresentation)

// EncodeInvertedIndexKeys takes in a key prefix and returns a slice of inverted index keys,
// one per unique path through the receiver.
