Detailed Description

Some conversion functions.

This contains functions to do some convenient conversion like uNumber2str(), uBytes2Hex() or uHex2Bytes().


Function Documentation

unsigned char UTILITE_EXP 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:
cthe ascii character
Returns:
the hexadecimal value
std::string UTILITE_EXP uBool2Str ( bool  boolean)

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

Parameters:
booleanthe boolean to convert in a string
Returns:
the string
std::string UTILITE_EXP 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:
bytesthe bytes array
bytesLenthe length of the bytes array
Returns:
the hexadecimal string
std::string UTILITE_EXP uFormat ( const char *  fmt,
  ... 
)

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

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

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

unsigned char UTILITE_EXP 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:
cthe hexadecimal value
rightPartIf we want the character corresponding to the right of left part (4 bits) of the byte value.
Returns:
the ascii character (in upper case)
std::vector<char> UTILITE_EXP 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:
hexthe hexadecimal string
Returns:
the bytes array
std::vector<char> UTILITE_EXP 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:
hexthe hexadecimal string
bytesLenthe hexadecimal string length
Returns:
the bytes array
std::string UTILITE_EXP 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:
hexthe hexadecimal string
Returns:
the ascii string
std::string UTILITE_EXP uNumber2Str ( unsigned int  number)

Convert a number (unsigned int) to a string.

Parameters:
numberthe number to convert in a string
Returns:
the string
std::string UTILITE_EXP uNumber2Str ( int  number)

Convert a number (int) to a string.

Parameters:
numberthe number to convert in a string
Returns:
the string
std::string UTILITE_EXP uNumber2Str ( float  number)

Convert a number (float) to a string.

Parameters:
numberthe number to convert in a string
Returns:
the string
std::string UTILITE_EXP uNumber2Str ( double  number)

Convert a number (double) to a string.

Parameters:
numberthe number to convert in a string
Returns:
the string
std::string UTILITE_EXP 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:
strthe string
beforethe character to be replaced by the new one
afterthe new character replacing the old one
Returns:
the modified string
std::string UTILITE_EXP 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:
strthe string
beforethe character to be replaced by the new one
afterthe new string replacing the old character
Returns:
the modified string
bool UTILITE_EXP 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:
strthe string to convert in a boolean
Returns:
the boolean
std::string UTILITE_EXP uToLowerCase ( const std::string &  str)

Transform characters from a string to lower case. Example :

 std::string str = "HELLO!";
 str = uToLowerCase(str, false);
 //str is now equal to "hello!"
Parameters:
strthe string
Returns:
the modified string
std::string UTILITE_EXP 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:
strthe string
Returns:
the modified string
