C++ (Cpp) keyForOptime Examples

Example #1

File: oplog_hack.cpp Project: stevelyall/mongol-db

/**
 * data and len must be the arguments from RecordStore::insert() on an oplog collection.
 */
StatusWith<RecordId> extractKey(const char* data, int len) {
    DEV invariant(validateBSON(data, len).isOK());

    const BSONObj obj(data);
    const BSONElement elem = obj["ts"];
    if (elem.eoo())
        return StatusWith<RecordId>(ErrorCodes::BadValue, "no ts field");
    if (elem.type() != bsonTimestamp)
        return StatusWith<RecordId>(ErrorCodes::BadValue, "ts must be a Timestamp");

    return keyForOptime(elem.timestamp());
}

Example #2

 */
