## Detailed Description

### template<typename T = UseRandom> class ThePEG::HandlerBaseT< T >

HandlerBaseT is a dummy abstract templated class used as base class to HandlerBase.

HandlerBaseT inherits from the Interfaced class adding some functionality such as easy acces to the RandomGenerator and the StandardModel object of the controlling EventGenerator object. The HandlerBaseT should only be used by the HandlerBase as a base class. The fact that it is templated allows classes which in turn inherits from HandlerBase to not explicitly depend on EventGenerator class if the inlined accessor funtions are not actually used. The only class which actually works as a template argument is UseRandom, which is used to generate random numbers.
