## Detailed Description

### template<class TYPE>
class SmartRef< TYPE >

Kernel objects: SmartRef.

Description: The SmartRef class allows transparent handling of object links within the data store. Links are unloaded a priori and will only be loaded "on demand", i.e. when dereferenced.

SmartRefs should behave in the same way as normal pointers; The SmartRef object in fact is a smart pointer construct intercepting the dereference operators.

When loading, the executed code resides in the non templated base class. This ensures, that the templated code is minimized and code blow up is inhibited.

Using SmartRefs StreamBuffers are able to also save the references on data conversion requests.

Base Class: SmartRefBase

Dependencies:

- Base class: GaudiKernel/SmartRefBase.h
