Function Documentation

◆ uAscii2Hex()

unsigned char uAscii2Hex ( const unsigned char & c )

Convert an ascii character to an hexadecimal value (right 4 bits). Characters can be in upper or lower case. Example :

unsigned char hex = uAscii2Hex('F');

// The results is hex = 0x0F;

See also: hex2ascii

Parameters

c	the ascii character

Returns: the hexadecimal value

Definition at line 221 of file UConversion.cpp.

◆ uBool2Str()

std::string uBool2Str ( bool boolean )

Convert a bool to a string. The format used is "true" and "false".

Parameters

boolean the boolean to convert in a string

Returns: the string

Definition at line 117 of file UConversion.cpp.

◆ uBytes2Hex()

std::string uBytes2Hex	(	const char *	bytes,
		unsigned int	bytesLen
	)

Convert a bytes array to an hexadecimal string. The resulting string is twice the size of the bytes array. The hexadecimal Characters are in upper case. Example :

char bytes[] = {0x3F};
std::string hex = uBytes2Hex(bytes, 1);
// The string constains "3F".

Parameters

bytes	the bytes array
bytesLen	the length of the bytes array

Returns: the hexadecimal string

Definition at line 136 of file UConversion.cpp.

◆ uFormat()

std::string uFormat	(	const char *	fmt,
			...
	)

Format a string like printf, and return it as a std::string

Definition at line 299 of file UConversion.cpp.

◆ uFormatv()

std::string uFormatv	(	const char *	fmt,
		va_list	ap
	)

Format a string like printf, and return it as a std::string

Definition at line 255 of file UConversion.cpp.

◆ uHex2Ascii()

unsigned char uHex2Ascii	(	const unsigned char &	c,
		bool	rightPart
	)

Convert hexadecimal (left or right part) value to an ascii character. Example :

unsigned char F = uHex2Ascii(0xFA, false);

unsigned char A = uHex2Ascii(0xFA, true);

See also: ascii2hex

Parameters

c	the hexadecimal value
rightPart	If we want the character corresponding to the right of left part (4 bits) of the byte value.

Returns: the ascii character (in upper case)

Definition at line 209 of file UConversion.cpp.

◆ uHex2Bytes() [1/2]

std::vector<char> uHex2Bytes ( const std::string & hex )

Convert an hexadecimal string to a bytes array. The string must be pair length. The hexadecimal Characters can be in upper or lower case. Example :

std::string hex = "1f3B";
std::vector<char> bytes = uHex2Bytes(hex);
// The array contains {0x1F, 0x3B}.

Parameters

hex	the hexadecimal string

Returns: the bytes array

Definition at line 156 of file UConversion.cpp.

◆ uHex2Bytes() [2/2]

std::vector<char> uHex2Bytes	(	const char *	hex,
		int	hexLen
	)

Convert an hexadecimal string to a bytes array. The string must be pair length. The hexadecimal Characters can be in upper or lower case. Example :

std::vector<char> bytes = uHex2Bytes("1f3B", 4);

// The array contains {0x1F, 0x3B}.

Parameters

hex	the hexadecimal string
bytesLen	the hexadecimal string length

Returns: the bytes array

Definition at line 161 of file UConversion.cpp.

◆ uHex2Str()

std::string uHex2Str ( const std::string & hex )

Convert an hexadecimal string to an ascii string. A convenient way when using only strings. The hexadecimal str MUST not contains any null values 0x00 ("00"). Think to use of hex2bytes() to handle 0x00 values. Characters can be in upper or lower case. Example :

std::string str = uHex2Str("48656C6C4F21");

// The string contains "Hello!".

See also: hex2bytes

Parameters

hex	the hexadecimal string

Returns: the ascii string

Definition at line 183 of file UConversion.cpp.

◆ uNumber2Str() [1/4]

std::string uNumber2Str ( unsigned int number )

Convert a number (unsigned int) to a string.

Parameters

number the number to convert in a string

Returns: the string

Definition at line 89 of file UConversion.cpp.

◆ uNumber2Str() [2/4]

std::string uNumber2Str ( int number )

Convert a number (int) to a string.

Parameters

number the number to convert in a string

Returns: the string

Definition at line 96 of file UConversion.cpp.

◆ uNumber2Str() [3/4]

std::string uNumber2Str ( float number )

Convert a number (float) to a string.

Parameters

number the number to convert in a string

Returns: the string

Definition at line 103 of file UConversion.cpp.

◆ uNumber2Str() [4/4]

std::string uNumber2Str ( double number )

Convert a number (double) to a string.

Parameters

number the number to convert in a string

Returns: the string

Definition at line 110 of file UConversion.cpp.

◆ uReplaceChar() [1/2]

std::string uReplaceChar	(	const std::string &	str,
		char	before,
		char	after
	)

Replace old characters in a string to new ones. Example :

std::string str = "Hello";
uReplaceChar(str, 'l', 'p');
// The results is str = "Heppo";

Parameters

str	the string
before	the character to be replaced by the new one
after	the new character replacing the old one

Returns: the modified string

Definition at line 31 of file UConversion.cpp.

◆ uReplaceChar() [2/2]

std::string uReplaceChar	(	const std::string &	str,
		char	before,
		const std::string &	after
	)

Replace old characters in a string with the specified string. Example :

std::string str = "Hello";
uReplaceChar(str, 'o', "oween");
// The results is str = "Helloween";

Parameters

str	the string
before	the character to be replaced by the new one
after	the new string replacing the old character

Returns: the modified string

Definition at line 44 of file UConversion.cpp.

◆ uStr2Bool()

bool uStr2Bool ( const char * str )

Convert a string to a boolean. The format used is : "false", "FALSE" or "0" give false. All others give true.

Parameters

str	the string to convert in a boolean

Returns: the boolean

Definition at line 131 of file UConversion.cpp.

◆ uToLowerCase()

std::string uToLowerCase ( const std::string & str )

std::string str = "HELLO!";
str = uToLowerCase(str, false);
//str is now equal to "hello!"

Parameters

str	the string

Returns: the modified string

Definition at line 75 of file UConversion.cpp.

◆ uToUpperCase()

std::string uToUpperCase ( const std::string & str )

Transform characters from a string to upper case. Example :

std::string str = "hello!";
str = uToUpperCase(str);
//str is now equal to "HELLO!"

Parameters

str	the string

Returns: the modified string
