Enum ExpressionFactory.UnaryOperator

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<ExpressionFactory.UnaryOperator>
    Enclosing class:
    ExpressionFactory

    public static enum ExpressionFactory.UnaryOperator
    extends java.lang.Enum<ExpressionFactory.UnaryOperator>
    Operators that apply to a single expression. The only unary operator that we support at present is ! (NOT) because this is very useful in constructing boolean expressions for while loops and conditionals.

      • values

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

        public static ExpressionFactory.UnaryOperator 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
