FBB::IOStream(3bobcat)   std::istream and std::ostream  FBB::IOStream(3bobcat)



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.
