iostream
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 differ-
ent streams. FBB:IOStream objects may, e.g., be associated with streams wrapped around pipes (see, e.g., FBB::IfdStream and FBB::OFd-
Stream), 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 avail-
able 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.
EXAMPLE
See the example provided with process(3bobcat).
