Detailed Description

Iterator for reading NDJSON (Newline Delimited JSON) data from a string.

This class provides an iterator interface for reading NDJSON formatted data. Each call to next() advances to the next JSON line, and getValue() returns the parsed JSON value.

Example

string ndjson = '{"id": 1}\n{"id": 2}\n{"id": 3}';
NdjsonIterator iter(ndjson);
while (iter.next()) {
    printf("Value: %y\n", iter.getValue());
}
