FromBase64()

static bvec_t crsysapi::Cnv::FromBase64 ( const std::string &  s )

static

Decodes a base64-encoded string as an array of bytes.

Parameters

s	Base64-encoded data to be decoded.

Returns

Array of bytes.

FromHex()

static bvec_t crsysapi::Cnv::FromHex ( const std::string &  s )

static

Decodes a hexadecimal-encoded string as an array of bytes.

Parameters

s	Hexadecimal-encoded data to be decoded.

Returns

Array of bytes.

ShortPathName()

static std::string crsysapi::Cnv::ShortPathName ( const std::wstring &  filePath )

static

Retrieve the Windows short path form of the specified path.

Parameters

filePath

Path name in wide characters.

Returns

Windows short path name or empty string if file does not exist.

Remarks

Windows only. The file path must exist. The short path is guaranteed to be ASCII. It may not have the same value on a different system.

ToBase64() [1/2]

static std::string crsysapi::Cnv::ToBase64 ( const bvec_t &  bv )

static

Parameters

bv	Input byte array.

Returns

Base64-encoded string.

ToBase64() [2/2]

static std::string crsysapi::Cnv::ToBase64 ( const std::string &  s )

static

Encodes a string as a base64-encoded string.

Parameters

s	String to be endoded.

Returns

Base64-encoded string.

cout << crsysapi::Cnv::ToBase64("abc") << endl;
// YWJj

ToHex() [1/2]

static std::string crsysapi::Cnv::ToHex ( const bvec_t &  bv )

static

Encodes an array of bytes as a hexadecimal-encoded string.

Parameters

bv	Input byte array.

Returns

Hexadecimal-encoded string.

ToHex() [2/2]

static std::string crsysapi::Cnv::ToHex ( const std::string &  s )

static

Encodes a string as a hexadecimal-encoded string.

Parameters

s	String to be endoded.

Returns

Hexadecimal-encoded string.

cout << crsysapi::Cnv::ToHex("abc") << endl;
