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.
