19Helper class to describe a consumer component.
20<p>
21There is unfortunately no unique determination of the data type from the component itself possible, thats why both component and data type have to be initialized and are stored in a compound. The class is intended to make bookkeeping easier.<p>
22<dl compact><dt><b>Note:</b></dt><dd>This class is only used for the <a class="el" href="group__alihlt__system.html">HLT integration into AliRoot</a>. </dd></dl>
