Class
Foam::dummyISstream
Description
Dummy input stream, which can be used as a placeholder for interfaces
taking an Istream or ISstream. Aborts at any attempt to read from it.
Note
The inheritance from an empty IStringStream is solely for convenience
of implementation and should not be relied upon.
