Member Functions
parse 
static int parse(
const std::string & s
);
Parses an integer value in decimal notation from the given string. Throws a SyntaxException if the string does not hold a number in decimal notation.
parse64
static Int64 parse64(
const std::string & s
);
Parses a 64-bit integer value in decimal notation from the given string. Throws a SyntaxException if the string does not hold a number in decimal notation.
parseFloat
static double parseFloat(
const std::string & s
);
Parses a double value in decimal floating point notation from the given string. Throws a SyntaxException if the string does not hold a floating-point number in decimal notation.
parseHex
static unsigned parseHex(
const std::string & s
);
Parses an integer value in hexadecimal notation from the given string. Throws a SyntaxException if the string does not hold a number in hexadecimal notation.
parseHex64
static UInt64 parseHex64(
const std::string & s
);
Parses a 64 bit-integer value in hexadecimal notation from the given string. Throws a SyntaxException if the string does not hold a number in hexadecimal notation.
parseUnsigned
static unsigned parseUnsigned(
const std::string & s
);
Parses an unsigned integer value in decimal notation from the given string. Throws a SyntaxException if the string does not hold a number in decimal notation.
parseUnsigned64
static UInt64 parseUnsigned64(
const std::string & s
);
Parses an unsigned 64-bit integer value in decimal notation from the given string. Throws a SyntaxException if the string does not hold a number in decimal notation.
tryParse
static bool tryParse(
const std::string & s,
int & value
);
Parses an integer value in decimal notation from the given string. Returns true if a valid integer has been found, false otherwise.
tryParse64
static bool tryParse64(
const std::string & s,
Int64 & value
);
Parses a 64-bit integer value in decimal notation from the given string. Returns true if a valid integer has been found, false otherwise.
tryParseFloat
static bool tryParseFloat(
const std::string & s,
double & value
);
Parses a double value in decimal floating point notation from the given string. Returns true if a valid floating point number has been found, false otherwise.
tryParseHex
static bool tryParseHex(
const std::string & s,
unsigned & value
);
Parses an unsigned integer value in hexadecimal notation from the given string. Returns true if a valid integer has been found, false otherwise.
tryParseHex64
static bool tryParseHex64(
const std::string & s,
UInt64 & value
);
Parses an unsigned 64-bit integer value in hexadecimal notation from the given string. Returns true if a valid integer has been found, false otherwise.
tryParseUnsigned
static bool tryParseUnsigned(
const std::string & s,
unsigned & value
);
Parses an unsigned integer value in decimal notation from the given string. Returns true if a valid integer has been found, false otherwise.
tryParseUnsigned64
static bool tryParseUnsigned64(
const std::string & s,
UInt64 & value
);
Parses an unsigned 64-bit integer value in decimal notation from the given string. Returns true if a valid integer has been found, false otherwise.
