13 \class TGenCollectionStreamer
14 \ingroup IO
15 
16 Streamer around an arbitrary container, which implements basic
17 functionality and iteration.
18 
19 In particular this is used to implement splitting and abstract
20 element access of any container. Access to compiled code is necessary
21 to implement the abstract iteration sequence and functionality like
22 size(), clear(), resize(). resize() may be a void operation.
