Method ArrayNull

decode_array.go:234–242

ArrayNull decodes the JSON value within an object or an array to a UnmarshalerJSONArray. v should be a pointer to an UnmarshalerJSONArray, if `null` value is encountered in JSON, it will leave the value v untouched, else it will create a new instance of the UnmarshalerJSONArray behind v.

(v interface{})

// if `null` value is encountered in JSON, it will leave the value v untouched,
// else it will create a new instance of the UnmarshalerJSONArray behind v.
func (dec *Decoder) ArrayNull(v interface{}) error {
	newCursor, err := dec.decodeArrayNull(v)
	if err != nil {
		return err
	}
	dec.cursor = newCursor
	dec.called |= 1
	return nil
}

// Index returns the index of an array being decoded.
