Class diagrams

This schema shows main interfaces in NMEA parser.

This diagram displays a hierarchy of NMEA messages.

This diagram displays a hierarchy of NMEA message parsers. Each type of NMEA message has its own parser. All supported types of parsers are registered in NmeaParser (see below).

NmeaParser class contains collection of parsers for each NMEA message. It decides what parser to use for specific NMEA string. GenericNmeaMessage class represents parsed NMEA string regardless of message type. It contains information about whether string is valid (checks CRC), components of NMEA message, message type, prefix. See sequence diagrams below for details.

Sequence diagrams

This sequence diagram describes the initialization process. As an example of parsers registration it shows RMC message parser creation and registration.

This sequence diagram describes the process of parsing of RMC NMEA string. The string, provided to NmeaParser goes to GenericNmeaMessage. It breaks it into components. After that NmeaParser checks type of NMEA message and calls corresponding parser.
