      APPROXIMATION
      If a good, and secure estimate is needed (the actual number can be lower or higher).
      EXACT
      If the exact number is needed.
      FAST_APPROXIMATION
      If a rough estimate is needed (the actual number can be lower or higher).

      • APPROXIMATION

        public static final Result.SizePrecision APPROXIMATION
        If a good, and secure estimate is needed (the actual number can be lower or higher). This is supposed to be faster than exact count, but slower than a fast approximation.
      • FAST_APPROXIMATION

        public static final Result.SizePrecision FAST_APPROXIMATION
        If a rough estimate is needed (the actual number can be lower or higher). This is supposed to be faster than a good approximation. It could be (for example) the expected cost of the query.

      • values

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

        public static Result.SizePrecision 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
