NAME

FBB::IOStreambuf - streambuf allowing input and output operations

SYNOPSIS

#include <bobcat/iostreambuf>
Linking option: -lbobcat

DESCRIPTION

This class implements a specialization of the std::streambuf class, allowing input operations from and output operations to different files. It is intended to be used in combination with FBB::IOStream, thus allowing all stream-based input and output operations using the same object without the need to use seek-operations. Using an FBB::IOStream object it is, e.g., possible to construct two-way communications using pipes, much like the facilities offered by sockets.

If the streams that will be associated with the IOStreambuf object support seeking, then the IOStreambuf will do so to. Seeking might also be available for a single stream (either the std::istream or the std::ostream).

When the IOStreambuf object goes out of scope, its associated std::ostream object is flushed.

NAMESPACE

FBB
All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.

INHERITS FROM

std::streambuf

CONSTRUCTORS

Copy and move constructors is not available.

MEMBER FUNCTIONS

All members of std::streambuf are available, as FBB::IOStreambuf inherits from these classes.

VIRTUAL PROTECTED MEMBER FUNCTIONS

The following std::streambuf member functions should only be called when the FBB::Streambuf object is associated with std::istream and std::ostream objects (i.e., they should not be called between the construction of a default FBB:IOStreambuf object and a subsequent call of IOStreambuf::open()):

The members listed in this section implement the tasks of comparably named virtual function in the class's private interface. This separates the redefinable interface from the user-interface. The class IOStreamBuf can, in accordance with Liskov's Substitution Principle, be used as a std:streambuf; but it also offers facilities for classes deriving from IOStreamBuf. These facilities are listed here.

EXAMPLE

See the example provided with process(3bobcat).
