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