FBB::IOStream - Combines std::istream and std::ostream features
Linking option: -lbobcat
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.
All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.
FBB::IOBuf (private inheritance),
The default constructor constructs an empty FBB::IOStream objects. It should not be used before its open member (see below) was called.
- 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.
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.
- 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.
- void clear():
This member clears the error states of the associated std::istream and std::ostream objects.
