Detailed Description

template<class Base_t, class CalibBase_t, class Parent_t>
class PhysicsTools::ProcessRegistry< Base_t, CalibBase_t, Parent_t >::Factory

Factory helper class to instantiate a processor.

The common base class of a processor can inherit from this helper class to provide a create() method to instantiate variable processor instances.
