Some conversion functions.
This contains functions to do some convenient conversion like uNumber2str(), uBytes2Hex() or uHex2Bytes().
Definition in file UConversion.h.
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;
c | the ascii character |
Definition at line 221 of file UConversion.cpp.
std::string uBool2Str | ( | bool | boolean | ) |
Convert a bool to a string. The format used is "true" and "false".
boolean | the boolean to convert in a string |
Definition at line 117 of file UConversion.cpp.
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".
bytes | the bytes array |
bytesLen | the length of the bytes array |
Definition at line 136 of file UConversion.cpp.
std::string uFormat | ( | const char * | fmt, |
... | |||
) |
Format a string like printf, and return it as a std::string
Definition at line 294 of file UConversion.cpp.
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.
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);
c | the hexadecimal value |
rightPart | If we want the character corresponding to the right of left part (4 bits) of the byte value. |
Definition at line 209 of file UConversion.cpp.
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}.
hex | the hexadecimal string |
Definition at line 156 of file UConversion.cpp.
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}.
hex | the hexadecimal string |
bytesLen | the hexadecimal string length |
Definition at line 161 of file UConversion.cpp.
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!".
hex | the hexadecimal string |
Definition at line 183 of file UConversion.cpp.
std::string uNumber2Str | ( | unsigned int | number | ) |
Convert a number (unsigned int) to a string.
number | the number to convert in a string |
Definition at line 89 of file UConversion.cpp.
std::string uNumber2Str | ( | int | number | ) |
Convert a number (int) to a string.
number | the number to convert in a string |
Definition at line 96 of file UConversion.cpp.
std::string uNumber2Str | ( | float | number | ) |
Convert a number (float) to a string.
number | the number to convert in a string |
Definition at line 103 of file UConversion.cpp.
std::string uNumber2Str | ( | double | number | ) |
Convert a number (double) to a string.
number | the number to convert in a string |
Definition at line 110 of file UConversion.cpp.
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";
str | the string |
before | the character to be replaced by the new one |
after | the new character replacing the old one |
Definition at line 31 of file UConversion.cpp.
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";
str | the string |
before | the character to be replaced by the new one |
after | the new string replacing the old character |
Definition at line 44 of file UConversion.cpp.
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.
str | the string to convert in a boolean |
Definition at line 131 of file UConversion.cpp.
std::string 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!"
str | the string |
Definition at line 75 of file UConversion.cpp.
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!"
str | the string |
