      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static Tristate 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

    • fromBoolean

      public static Tristate fromBoolean(boolean val)
      Returns a Tristate from a boolean.
      Parameters:
      val - the boolean value
      Returns:
      TRUE or FALSE, if the value is true or false, respectively.

    • fromNullableBoolean

      public static Tristate fromNullableBoolean(@Nullable Boolean val)
      Returns a Tristate from a nullable boolean.

      Unlike fromBoolean(boolean), this method returns UNDEFINED if the value is null.

      Parameters:
      val - the boolean value
      Returns:
      UNDEFINED, TRUE or FALSE, if the value is null, true or false, respectively.

    • fromOptionalBoolean

      Parameters:
      val - the optional boolean value
      Returns:
      UNDEFINED, TRUE or FALSE, if the value is empty, true or false, respectively.

    • asBoolean

      public boolean asBoolean()
      Returns the value of the Tristate as a boolean.

      A value of UNDEFINED converts to false.

      Returns:
      a boolean representation of the Tristate.

    • toAdventureTriState

      public TriState toAdventureTriState()
      Returns the equivalent Adventure TriState.
      Returns:
      equivalent Adventure TriState
