Enum JSONOptions.ConversionMode

    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      Decimal128
      JSON numbers are decoded to CBOR as their closest-rounded approximation to an IEEE 854 decimal128 value, using the rules for the EDecimal form of that approximation as given in the CBORObject.FromObject(EDecimal) method.
      Double
      JSON numbers are decoded to CBOR as their closest-rounded approximation as 64-bit binary floating-point numbers.
      Full
      JSON numbers are decoded to CBOR using the full precision given in the JSON text.
      IntOrFloat
      A JSON number is decoded to CBOR either as a CBOR integer (major type 0 or 1) if the JSON number represents an integer at least -(2^53)+1 and less than 2^53, or as their closest-rounded approximation as 64-bit binary floating-point numbers otherwise.
      IntOrFloatFromDouble
      A JSON number is decoded to CBOR either as a CBOR integer (major type 0 or 1) if the number's closest-rounded approximation as a 64-bit binary floating-point number represents an integer at least -(2^53)+1 and less than 2^53, or as that approximation otherwise.

      • Full

        public static final JSONOptions.ConversionMode Full
        JSON numbers are decoded to CBOR using the full precision given in the JSON text. The number will be converted to a CBOR object as follows: If the number's exponent is 0 (after shifting the decimal point to the end of the number without changing its value), using the rules given in the CBORObject.FromObject(EInteger) method; otherwise, using the rules given in the CBORObject.FromObject(EDecimal) method. An exception in version 4.x involves negative zeros; if the negative zero's exponent is 0, it's written as a CBOR floating-point number; otherwise the negative zero is written as an EDecimal.

      • Double

        public static final JSONOptions.ConversionMode Double
        JSON numbers are decoded to CBOR as their closest-rounded approximation as 64-bit binary floating-point numbers. (In some cases, numbers extremely close to zero may underflow to positive or negative zero, and numbers of extremely large magnitude may overflow to infinity.).

      • IntOrFloat

        public static final JSONOptions.ConversionMode IntOrFloat
        A JSON number is decoded to CBOR either as a CBOR integer (major type 0 or 1) if the JSON number represents an integer at least -(2^53)+1 and less than 2^53, or as their closest-rounded approximation as 64-bit binary floating-point numbers otherwise. For example, the JSON number 0.99999999999999999999999999999999999 is not an integer, so it's converted to its closest floating-point approximation, namely 1.0. (In some cases, numbers extremely close to zero may underflow to positive or negative zero, and numbers of extremely large magnitude may overflow to infinity.).

      • IntOrFloatFromDouble

        public static final JSONOptions.ConversionMode IntOrFloatFromDouble
        A JSON number is decoded to CBOR either as a CBOR integer (major type 0 or 1) if the number's closest-rounded approximation as a 64-bit binary floating-point number represents an integer at least -(2^53)+1 and less than 2^53, or as that approximation otherwise. For example, the JSON number 0.99999999999999999999999999999999999 is the integer 1 when rounded to its closest floating-point approximation (1.0), so it's converted to the CBOR integer 1 (major type 0). (In some cases, numbers extremely close to zero may underflow to zero, and numbers of extremely large magnitude may overflow to infinity.).

      • Decimal128

        public static final JSONOptions.ConversionMode Decimal128
        JSON numbers are decoded to CBOR as their closest-rounded approximation to an IEEE 854 decimal128 value, using the rules for the EDecimal form of that approximation as given in the CBORObject.FromObject(EDecimal) method.

      • values

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

      • valueOf

        public static JSONOptions.ConversionMode 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
