Detailed Description

implementation of various functions for streaming.

this functionality is essential for usage of various types as property for the various Gaudi components

Attention

the implementation of the specific specializations must be done before the inclusion of this file

Todo:

ToStream.h : reimplement in terms of functors, to allow easier specializations

Definition in file ToStream.h.
