public class NmeaParserLib
extends java.lang.Object

Here's how NmeaParserLib parses sentences: first, it ignores errors on a per-field basis. Blank fields are interpreted as 0. Second, it parses a sentence until the fields run out. If there aren't enough fields in a sentence, it uses all the fields it finds. The goal of this parsing strategy is to handle anything that even kind of looks like GPS data. It don't log errors when it finds them, and it is very permissive about what makes a valid sentence.

Method Detail

parseDouble

public static double parseDouble(java.lang.String s)

More tolerant for all the strange fields a GPS will hand us. Ignores parsing errors and just returns a 0. Explicitly converts blanks to 0's.

Parameters:

s -

Returns:

parseInt

public static int parseInt(java.lang.String s)

More tolerant for all the strange fields a GPS will hand us. Ignores parsing errors and just returns a 0. Explicitly converts blanks to 0's.

Parameters:

s -

Returns:

parseLatitude

public static double parseLatitude(java.lang.String latitudeString,
                                   java.lang.String direction)

parseLongitude

public static double parseLongitude(java.lang.String longitudeString,
                                    java.lang.String direction)

parseUtc

public static double parseUtc(java.lang.String utc)

Returns the number of milliseconds that have elapsed in this day.

Parameters:

utc -

Returns:
