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.
