class TGenCollectionProxy: public TVirtualCollectionProxy


 TGenCollectionProxy

 Proxy around an arbitrary container, which implements basic
 functionality and iteration.

 In particular this is used to implement splitting and abstract
 element access of any container. Access to compiled code is necessary
 to implement the abstract iteration sequence and functionality like
 size(), clear(), resize(). resize() may be a void operation.
