Enum ConditionResult

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<ConditionResult>

    public enum ConditionResult
    extends java.lang.Enum<ConditionResult>
    This enum defines a set of values which may be used to represent the result of a Boolean evaluation in which the result may be undefined.

      • values

        public static ConditionResult[] 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 (ConditionResult c : ConditionResult.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static ConditionResult valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
      • invert

        public ConditionResult invert()
        Retrieves the condition result value which is the inverse of this value. The inverse of TRUE is FALSE, and vice-versa. The inverse of UNDEFINED is UNDEFINED.
        Returns:
        The condition result value which is the inverse of this value.
      • invert

        public static ConditionResult invert​(ConditionResult r)
        Retrieves the condition result value which is the inverse of the provided result. The inverse of TRUE is FALSE, and vice-versa. The inverse of UNDEFINED is UNDEFINED.
        Parameters:
        r - The condition result value for which to retrieve the inverse value. It must not be null.
        Returns:
        The condition result value which is the inverse of the provided result.
      • toString

        public java.lang.String toString()
        Retrieves a string representation of this condition result value.
        Overrides:
        toString in class java.lang.Enum<ConditionResult>
        Returns:
        A string representation of this condition result value.
