Detailed Description

template<class TYPE>
class SmartIF< TYPE >

Small smart pointer class with automatic reference counting for IInterface.

SmartIF simplifies the interaction with components in Gaudi by implementing an automatic reference counting and the casting (via IInterface::queryInterface).
