[Scip] HOW TO USE SCIP_VARDATA

[Gregor Hendel]

Hi Diego,

using C++, you can create customized variable data by subclassing 
scip:ObjVardata from objvardata.h 
<http://scip.zib.de/doc/html_devel/objvardata_8h_source.php>. Variables 
which should use your variable data can be created by calling
SCIPcreateObjVar() 
<http://scip.zib.de/doc/html_devel/objvardata_8h.php#a8c9be3e5b510487d59fdc065464e401b> 
instead of SCIPcreateVar(). The VRP-example uses the latter method for 
the priced variables because no custom variable data is necessary there.
In order to access your variable data later, you need use 
SCIPgetObjVardata().

Hope that helps,
Gregor
