FBB::Eoi - std::streambuf class offering an eoi manipulator
#include <bobcat/eoi> Linking option: -lbobcat
The class Eoi inherits from std::streambuf and may therefore be used as a base class of classes specializing std::streambuf. It is particularly useful for classes implementing output operations, as it can be used to specify the `true end’ of the generated output. E.g., an std::istream in object may insert its contents into a std::ostream out object using the familiar out << in.rdbuf() expression, but that doesn’t allow out to conclude that it has received all of its information. Sometimes additional actions are required to complete the output (this happens with, e.g., EncryptBuf objects (cf. encryptbuf(3bobcat)) where after encrypting all input padding characters may have to be added to the encrypted document). If out is initialized with the address of an EncryptBuf std::streambuf then the true end of the input can be indicated by inserting the eoi manipulator. The resulting expression becomes std::cout << in.rdbuf() << eoi, and the manipulator ensures that the correct padding is handled.
FBB All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.
o Eoi(): Analogously to std::streambuf only a default protected constructor is available. Copy and move constructors (and assignment operators) are not available.
All members of std:streambuf are available, as FBB::Eoi inherits from these classes.
VIRTUAL MEMBER FUNCTION
o virtual void eoi_(): The virtual member function eoi_ is a private member that can be overridden by derived classes. By default it performs no actions.
o std::ostream &FBB::eoi(std::ostream &out): If the ostream out’s streambuf’s address can be downcasted to an Eoi * then its eoi_ member is called. Otherwise the manipulator performs no actions, and merely returns out.
See the example provided in the encryptbuf(3bobcat) man-page
