<h2>Description</h2>
<div class="description">
<p>This class implements an ostream interface to a <a href="Poco.Logger.html" title="class Poco::Logger">Logger</a>. </p>
<p>The stream's buffer appends all characters written to it to a string. As soon as a CR or LF (std::endl) is written, the string is sent to the <a href="Poco.Logger.html" title="class Poco::Logger">Logger</a>, with the current priority. </p>
<p>Usage example: </p>
<pre>LogStream ls(someLogger);
ls << "Some informational message" << std::endl;
ls.error() << "Some error message" << std::endl;
</pre>
