    • Field Detail

      • operatorsByPrecedence

        public static final java.util.List<ArithmeticOperator> operatorsByPrecedence
        A list of all the operators in this in order of decreasing precedence

    • Method Detail

      • values

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

      • valueOf

        public static ArithmeticOperator 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

      • hasPrecedenceOver

        public boolean hasPrecedenceOver​(ArithmeticOperator op)
        Returns true if this operator has precedence over the given operator

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class java.lang.Enum<ArithmeticOperator>
