Detailed Description

A wrapper class for the most commonly used encoding and decoding algorithms. A collection of commonly used encoding and decoding algorithms.

Currently there is support for encoding and decoding input using base64, uu and the quoted-printable specifications.

Usage:

QCString input = "Aladdin:open sesame"; QCString result = KCodecs::base64Encode(input); cout << "Result: " << result.data() << endl;

Output should be Result: QWxhZGRpbjpvcGVuIHNlc2FtZQ==

The above example makes use of the convenience functions (ones that accept/return null-terminated strings) to encode/decode a string. If what you need is to encode or decode binary data, then it is highly recommended that you use the functions that take an input and output QByteArray as arguments. These functions are specifically tailored for encoding and decoding binary data.

Member Function Documentation

QCString KCodecs::quotedPrintableEncode const QByteArray in,
bool  useCRLF = true
[static]
 

Encodes the given data using the quoted-printable algorithm.

Parameters:
in data to be encoded.
useCRLF if true the input data is expected to have CRLF line breaks and the output will have CRLF line breaks, too.
Returns:
quoted-printable encoded data.

Definition at line 150 of file kmdcodec.cpp.

Referenced by quotedPrintableEncode().

QCString KCodecs::quotedPrintableEncode const QCString str,
bool  useCRLF = true
[static]
 

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Same as above except it accepts a null terminated string instead an array.

Parameters:
str data to be encoded.
useCRLF if true the input data is expected to have CRLF line breaks and the output will have CRLF line breaks, too.
Returns:
quoted-printable encoded data.

Definition at line 157 of file kmdcodec.cpp.

References QCString::isEmpty(), QCString::length(), and quotedPrintableEncode().

void KCodecs::quotedPrintableEncode const QByteArray in,
QByteArray out,
bool  useCRLF
[static]
 

Encodes the given data using the quoted-printable algorithm.

Use this function if you want the result of the encoding to be placed in another array which cuts down the number of copy operation that have to be performed in the process. This is also the preferred method for encoding binary data.

NOTE: the output array is first reset and then resized appropriately before use, hence, all data stored in the output array will be lost.

Parameters:
in data to be encoded.
out decoded data.
useCRLF if true the input data is expected to have CRLF line breaks and the output will have CRLF line breaks, too.
Returns:
quoted-printable encoded data.

QCString KCodecs::uuencode const QByteArray in  )  [static]
 

Encodes the given data using the uuencode algorithm.

The output is split into lines starting with the number of encoded octets in the line and ending with a newline. No line is longer than 45 octets (60 characters), excluding the line terminator.

Parameters:
in the data to be uuencoded
Returns:
a uuencoded data.

void KCodecs::uuencode const QByteArray in,
QByteArray out
[static]
 

Encodes the given data using the uuencode algorithm.

Use this function if you want the result of the encoding to be placed in another array and cut down the number of copy operation that have to be performed in the process. This is the preffered method for encoding binary data.

NOTE: the output array is first reset and then resized appropriately before use, hence, all data stored in the output array will be lost.
