A traffic message.
A message is the atomic element of traffic information, referring to a particular condition at a given location.
If no updates are received for a message, it should be discarded after both expiration_time and end_time (if specified) have elapsed.
| time_t traffic_message::end_time |
How long the condition is expected to last (optional, 0 if not set).
Referenced by traffic_message_dump_to_stderr(), traffic_message_is_valid(), and traffic_message_new().
| int traffic_message::event_count |
The number of events in events.
Referenced by traffic_message_add_event(), traffic_message_destroy(), traffic_message_dump_to_stderr(), traffic_message_is_valid(), traffic_message_new(), traffic_message_new_short(), and traffic_message_parse_events().
| struct traffic_event** traffic_message::events |
Points to an array of pointers to the events for this message.

| time_t traffic_message::expiration_time |
How long the message should be considered valid.
Referenced by traffic_message_dump_to_stderr(), traffic_message_is_valid(), traffic_message_new(), traffic_message_new_cancellation(), traffic_message_new_short(), and traffic_process_messages_int().
| char* traffic_message::id |
An identifier, which remains stable over the entire lifecycle of the message. The colon (:) is a reserved character to separate different levels of source identifiers from each other and from the local message identifier.

| int traffic_message::is_cancellation |
If true, this message is a cancellation message, indicating that existing messages with the same ID should be deleted or no longer considered current. All other attributes of a cancellation message should be ignored.
Referenced by traffic_message_dump_to_stderr(), traffic_message_is_valid(), and traffic_message_new().
| int traffic_message::is_forecast |
If false, the message describes a current situation. If true, it describes an expected situation in the future.
Referenced by traffic_message_dump_to_stderr(), traffic_message_new(), and traffic_message_new_short().
| struct traffic_location* traffic_message::location |
The location to which this message refers.

| time_t traffic_message::receive_time |
When the message was first received by the source, should be kept stable across all updates.
Referenced by traffic_message_dump_to_stderr(), traffic_message_is_valid(), traffic_message_new(), traffic_message_new_cancellation(), and traffic_message_new_short().
