| <p>The logger with this feature automatically registers an attribute with the specified on construction value, which is a channel name. The channel name can be modified through the logger life time, either by calling the <code class="computeroutput">channel</code> method or by specifying the name in the logging statement.</p> |
| <p>The type of the channel name can be customized by providing it as a template parameter to the feature template. By default, a string will be used. </p> |
