NAME

       FBB::Eoi - std::streambuf class offering an eoi manipulator

SYNOPSIS

       #include <bobcat/eoi>
       Linking option: -lbobcat

DESCRIPTION

       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 content  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.

NAMESPACE

       FBB
       All constructors, members, operators and manipulators, mentioned  in  this  man-page,  are
       defined in the namespace FBB.

INHERITS FROM

       std::streambuf

PROTECTED CONSTRUCTOR

       o      Eoi():
              Analogously to std::streambuf only a default protected constructor is available.

       Copy and move constructors (and assignment operators) are not available.

MEMBER FUNCTIONS

       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.

MANIPULATORS

       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.
