New Revision: 46551
URL: http://svn.boost.org/trac/boost/changeset/46551
Log:
- Minor update of class traversals
- Fixed some bugs in the meta-path related templates
- Added a new meta-path axis (parent)
- The interface of the visitors has been updated
- Added a new sample visitor showing what meta-path
expressions can currently do
- Tested with MSVC++ 2008 EE On Vista
