Detailed Description

Some useful string operations.

Function Documentation

ToString()

template<class T >

std::string StrUtils::ToString	(	T	value,
		bool *	ok = nullptr
	)

Converts a value to string.

If given, ok is set to true/false on success/failure. Warning: To avoid unnecessary problems, always give full template qualifier e.g. ToString<int>

FromString()

template<class T >

T StrUtils::FromString	(	const std::string &	str,
		bool *	ok = nullptr
	)

Converts a value to string.

If given, ok is set to true/false on success/failure. Warning: To avoid unnecessary problems, always give full template qualifier e.g. FromString<int>

HexStringToInt()

unsigned int StrUtils::HexStringToInt

(

const std::string &

str

)

Converts string of hex characters to int.

Format()

std::string StrUtils::Format	(	const char *	fmt,
			...
	)

Replacement for sprintf()

Replace()

std::string StrUtils::Replace	(	const std::string &	str,
		const std::string &	oldStr,
		const std::string &	newStr
	)

Returns a string with every occurence of oldStr in str replaced to newStr.

UnicodeCharToUtf8()

std::string StrUtils::UnicodeCharToUtf8

(

unsigned int

ch

)

Converts a wide Unicode char to a single UTF-8 encoded char.

UnicodeStringToUtf8()

std::string StrUtils::UnicodeStringToUtf8

(

const std::wstring &

str

)

Converts a wide Unicode string to a UTF-8 encoded string.

Utf8CharToUnicode()

unsigned int StrUtils::Utf8CharToUnicode

(

const std::string &

ch

)

Converts a UTF-8 encoded single character to wide Unicode char.

Utf8StringToUnicode()

std::wstring StrUtils::Utf8StringToUnicode

(

const std::string &

str

)

Converts a UTF-8 encoded string to wide Unicode string.

Utf8CharSizeAt()

int StrUtils::Utf8CharSizeAt	(	const std::string &	str,
		unsigned int	pos
	)

Returns the size in bytes of UTF-8 character at given pos in a UTF-8 str.

Utf8StringLength()

std::size_t StrUtils::Utf8StringLength

(

const std::string &

str

)

Returns the length in characters of UTF-8 string str.
