FBB::IQuotedPrintableStreambuf - Input Filtering stream buffer doing quoted printable conversions
#include <bobcat/iquotedprintablestreambuf>
Linking option: -lbobcat
The information made available by IQuotedPrintableStreambuf objects is either quoted-printable encoded or decoded. The information to convert is read by IQuotedPrintableStreambuf objects via std::istream objects.
The class IQuotedPrintableStreambuf is a class template, using a FBB::CryptType template non-type parameter. Objects of the class FBB::IQuotedPrintableStreambuf<FBB::ENCODE> encode the information they receive, objects of the class FBB::IQuotedPrintableStreambuf<FBB::DECODE> decode the information they receive. See also section ENUMERATION below.
Quoted-printable encoding is sometimes used in e-mail attachments (See also https://en.wikipedia.org/wiki/Quoted-printable and https://www.ietf.org/rfc/rfc2045.txt (section 6.7)). Its main characteristics are:
FBB
All constructors, members, operators and manipulators, mentioned in this
man-page, are defined in the namespace FBB.
FBB::IFilterStreambuf
All members of FBB::IFilterStreambuf are available, as IQuotedPrintableStreambuf inherits from this class.
Overloaded move and/or copy assignment operators are not available.
IQuotedPrintableStreambuf objects either encode or decode quoted-printable information. IQuotedPrintableStreambuf objects of the class FBB::IQuotedPrintableStreambuf<FBB::ENCODE> encode the data they receive, IQuotedPrintableStreambuf objects of the class FBB::IQuotedPrintableStreambuf<FBB::DECODE> decode the data they receive.
The values ENCODE and DECODE are defined in the enum CryptType, defined in the FBB namespace.
Copy- and move constructors are not available.
The example shows the construction of IQuotedPrintableStreambuf<ENCODE> objects encode which are used to initialize a std::istream object. The information read from this istream is quoted-printable encoded.
IQuotedPrintableStreambuf<DECODE> objects read quoted-printable encoded information from std::istream objects, decoding the information.
The std::istream din object is initialized with the IQuotedPrintableStreambuf<DECODE> object, and its contents is sent to std::cout. The information that is presented at std::cin and that appears at std::cout should be identical.
