Event Class

The Event class represents the smallest data unit in ChronoLog. Each Event contains a timestamp, client ID, an index, and a log record.

Constructor

Event::Event(chrono_time event_time = 0, ClientId client_id = 0, chrono_index index = 0, std::string const &record = std::string())

• Creates an Event object.
• event_time: The timestamp of the event.
• client_id: The client ID that generated the event.
• index: The event index for ordering.
• record: The actual data record of the event.

Getters

uint64_t Event::time() const

• Returns the timestamp of the Event.

ClientId const &Event::client_id() const

• Returns the client ID of the Event.

uint32_t Event::index() const

• Returns the index of the Event.

std::string const &Event::log_record() const

• Returns the log record of the Event.

Operators

bool Event::operator==(const Event &other) const

• Checks if two Events are equal based on event_time, client_id, and eventIndex.

bool Event::operator!=(const Event &other) const

• Checks if two Events are different.

bool Event::operator<(const Event &other) const

• Compares Events based on event_time, then client_id, and finally eventIndex.

std::string Event::toString() const

• Returns a string representation of the Event in the format: {Event:<eventTime>:<clientId>:<eventIndex>:<logRecord>}
