The prefix is specified in the constructor (as well as the destination ostream). A newline must be passed to the stream, and then the prefix will be prepended to the next line. For example, \begin{DoxyCode} PrefixedOutStream outstr(std::cout, \textcolor{stringliteral}{"[TEST] "}); outstr << \textcolor{stringliteral}{"Hello world I like "} << 7.5; outstr << \textcolor{stringliteral}{"...Continue"} << std::endl; outstr << \textcolor{stringliteral}{"After the CR\(\backslash\)n"} << std::endl; \end{DoxyCode} would give, on std\+::cout, \begin{DoxyCode} [TEST] Hello world I like 7.5...Continue [TEST] After the CR [TEST] \end{DoxyCode} These objects are used for the \doxyref{mlpack\+::\+Log}{p.}{classmlpack_1_1Log} levels (D\+E\+B\+UG, I\+N\+FO, W\+A\+RN, and F\+A\+T\+AL).
