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::IOStreambuf (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  De  copy  constructor  is
              available as well.

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.
