      public static GhfsStatistic[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static GhfsStatistic valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name
      NullPointerException - if the argument is null

    • getSymbol

      public String getSymbol()
      the name of the statistic

    • fromSymbol

      public static GhfsStatistic fromSymbol(String symbol)
      Get a statistic from a symbol.
      Parameters:
      symbol - statistic to look up
      Returns:
      the value or null.

    • getDescription

      public String getDescription()
      The description of the Statistic

    • toString

      public String toString()
      The string value is simply the symbol. This makes this operation very low cost.
      Overrides:
      toString in class Enum<GhfsStatistic>
      Returns:
      the symbol of this statistic.

    • getType

      public StatisticTypeEnum getType()
      What type is this statistic?
      Returns:
      the type.
