Subject: *** MAJOR CHANGE *** NOT WORKING YET !!!
X-Git-Tag: EED.02Oct2009~50
X-Git-Url: https://git.creatis.insa-lyon.fr/pubgit/?a=commitdiff_plain;h=b8fe96fbebd153e92de1f1bfcad48ad009365df5;p=bbtk.git

*** MAJOR CHANGE *** NOT WORKING YET !!!
We have removed the bbUserConstructor/CopyConstructor/Destructor methods
And created the bbUserSetDefaultValues / InitializeProcessing / FinalizeProcessing which are better !
Related changes have been made in:
*the kernel
*bbfy
*the std-template.xml of bbCreateBlackBox
*package std

All other packages have to be patched !!!!
