Field Detail

sentenceDef

public static final java.lang.String[] sentenceDef

Definition of understood NMEA0183 sentences. The values given here as symbolic names are taken as field names of the info object given to the parse method; values from the sentence are automatically converted to the field's type in the info object. E.g. the definition of
$GPTST,lat,long
specifies a new message that has the header $GPTST, and two parameters lat and long. Those two values are automatically parsed and stored inside the GPSInfo class, in the fields with names lat and long. The type of the value is automatically converted to fit the type of the fields.
