NAME

       FBB::IOStream - Combines std::istream and std::ostream features

SYNOPSIS

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

DESCRIPTION

       This  class  combines  the  features  of  the  std::istream  and std::ostream classes. The
       std::istream and std::ostream may be physically different  streams.  FBB:IOStream  objects
       may,  e.g., be associated with streams wrapped around pipes (see, e.g., FBB::IfdStream and
       FBB::OFdStream), to construct bi-directional pipes.

NAMESPACE

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

INHERITS FROM

       FBB::IOBuf (private inheritance),
       std::istream,
       std::ostream

CONSTRUCTORS

       o      IOStream():
              The default constructor constructs an empty FBB::IOStream objects. It should not be
              used before its open member (see below) was called.

       o      IOStream(std::istream &in, std::ostream &out):
              This  constructor  associates  the  IOStream  object  with  a  std::istream  and  a
              std::ostream.  All  output  operations  will  be passed on to the std::ostream, all
              input operations to the std::istream. The streams passed to IOStream should outlive
              the  IOStream  object.  This  constructor  performs  the  actions  of  the  default
              constructor and then calls the IOStream::open member

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

MEMBER FUNCTIONS

       All members of std::istream and std::ostream  are  available,  as  FBB::IOStream  inherits
       from  these  classes.  Furthermore,  when  switching between std::istream and std::ostream
       operations, no intermediate seekg() or seekp() operation will normally be required,  since
       the base classes will normally be associated with physically different streams.

       o      void open(std::istream &in, std::ostream &out):
              This   member  (re)associates  the  IOStream  object  with  a  std::istream  and  a
              std::ostream. All output operations will be passed  on  to  the  std::ostream,  all
              input  operations  to  the  std::istream.  The  streams passed to IOStream() should
              outlive the IOStream object. If this  member  is  called  for  an  IOStream  object
              already associated with an std::ostream object, the already associated std::ostream
              object is flushed before setting up the new association.

       o      void clear():
              This member clears the error states of the associated std::istream and std::ostream
              objects.
