An Ostream is an abstract base class for all output systems (streams, files, token lists,...
Definition: Ostream.H:62
Ostream & writeEntry(const keyType &key, const T &value)
Write a keyword/value entry.
Definition: Ostream.H:239
Ostream & writeEntryIfDifferent(const word &key, const T &value1, const T &value2)
Write a keyword/value entry only when the two values differ.
Definition: Ostream.H:251
cpuInfo()
Construct and populate with information.
Definition: cpuInfo.C:37
virtual bool write()
Write the output fields.
