org.ka2ddo.gps.GPSParser
public class GPSParser
- extends java.lang.Object
This class collects GPS data from GPS data sources and accumulates current
position data for use by other parts of the application.

Parse an NMEA-0183 standard data sentence into GPS data structure values. |

split(java.lang.String line,
char separator)
This is a more optimized version of String.split() that doesn't require
compiling and evaluating regular expression patterns to do it, thereby
saving chunks of transient heap (and probably some CPU time as well). |

parseNMEA0183DataLine
public static java.lang.Object parseNMEA0183DataLine(java.lang.String line,
GpsFix fix,
SatelliteCatalog satCatalog,
java.lang.String source)
- Parse an NMEA-0183 standard data sentence into GPS data structure values.
- Parameters:
line
- String line to parsefix
- GpsFix data structure to populate, or null if a new one should be allocatedsatCatalog
- SatelliteCatalog data structure to populate, or null if a new one should be allocatedsource
- callsign of source (used only for error messages)
- Returns:
- populated data structure if valid sentence parsed, "ASTRAL" if the sentence was
a DeLorme TripMate trying to initialize, or null if parse failed

split
protected static java.lang.String[] split(java.lang.String line,
char separator)
- This is a more optimized version of String.split() that doesn't require
compiling and evaluating regular expression patterns to do it, thereby
saving chunks of transient heap (and probably some CPU time as well).
- Parameters:
line
- the String to split at occurrences of the separatorseparator
- the char delimiting substrings of the line
- Returns:
- array of Strings split at the various points the separator appears
