<div>This is indeed a limitation. Currently in clas12 we do use the same parameters as reconstruction, because they come from a common DB. The calculations of parameters are done using the reconstruction java library.<br></div>
<div>If the reconstruction is in C++ this can be achieved with the plugin capability of gemc - using a shared library that is used in reconstruction as well.</div></div></div></div></blockquote><div><br></div><div>This is something I'd like to know more about.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word"><div><div>

<div>Admittedly gemc was not designed to be part of a framework, however a partial re-design is in process that could help in that regard.
