Detailed Description

All libraries registered with the Factory class must have constructors with no arguments. Also, they must expose symbols for onstruction and destruction, declaring them external as in the following example:

extern "C" LcgInfo::Querier* <the Constructor>() { return new <invoking the real Constructor of your class>; }

extern "C" void <the Destructor(LcgInfo::Querier *p) { delete p; }
