      • values

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

        public static QueueOrigin 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
      • getInstance

        protected static QueueOrigin getInstance​(int value)
        Return the enumeration value that corresponds to an integer value of interest.
        Parameters:
        value - The integer value.
        Returns:
        The enumeration value.
      • getValue

        public int getValue()
        Get the integer value corresponding to this enumeration value.
        Returns:
        The integer value.
