Sorry, I have send the message before completing it:
unsigned int osg::computeVisitorType(const std::string& type_id)
{
return some_hash(type_id);
}
This would enable the possibility to check out which type of visitor is
currently traversing the node. Also in future releases or in external
applications with just different visitors there would be a possibility to
detect visitor types in a simple way.
All osg visitors might be named with "osg_" prefix and hence make them more or
less unique (of course in the limitation of the hash function used).
What about that idea?
