Enum Fix

  • All Implemented Interfaces:
    Serializable, Comparable<Fix>

    public enum Fix
    extends Enum<Fix>
    Type of GPS fix (position derived from measuring external reference points). The Standard Positioning Service (SPS) can be two- or three-dimensional, or use differential GPS for increased accuracy. The Precise Positioning Service (PPS) is a military signal.

    This enumeration value can be encoded in GPS Exchange Format (GPX) with the following strings: "none", "2d", "3d", "dgps" and "pps". When reading such data, Fix instances can be a property value of the features returned by the GPX reader.

    • Enum Constant Detail

      • NONE

        public static final Fix NONE
        GPS has no fix. Note that this is a different meaning than "the fix information is unknown".
      • TWO_DIMENSIONAL

        public static final Fix TWO_DIMENSIONAL
        Two-dimensional fix. This requires the signal of at least 3 satellites.
      • THREE_DIMENSIONAL

        public static final Fix THREE_DIMENSIONAL
        Three-dimensional fix. This requires the signal of at least 4 satellites.
      • PRECISE

        public static final Fix PRECISE
        Precise Positioning Service (PPS) used. This is a military signal. (Note: the alternative is Standard Positioning Service – SPS).

      • values

        public static Fix[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (Fix c : Fix.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static Fix valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        Illegal­Argument­Exception - if this enum type has no constant with the specified name
        Null­Pointer­Exception - if the argument is null
      • fromGPX

        public static Fix fromGPX​(String name)
        Returns the enumeration value from the given GPX name, or null if none. Recognized values are "none", "2d", "3d", "dgps" and "pps", ignoring case.
        Parameters:
        name - the GPX name (case insensitive) for which to get an enumeration value.
        Returns:
        the enumeration value for the given GPX name, or null if the given name was null or unrecognized.
      • toGPX

        public String toGPX()
        Returns the string representation in GPS Exchange Format (GPX). Returned value can be "none", "2d", "3d", "dgps" or "pps",
        Returns:
        the GPX enumeration value.
