## Detailed Description

### template<class TYPE>
class SmartRefVector< TYPE >

Kernel objects: SmartRefVector.

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

SmartRefVectors should behave in the same way as normal vectors of pointers;

Using SmartRefVectors the environment of the vector is automatically propagated to each contained reference.

In order to speed things up, an attempt was made to avoid any virtual functions.

Base Class: STL vector

Dependencies:

- Base class: vector
- SmartRef constructs: Gaudi/Kernel/SmartRef.h
