Re: [osg-users] DEEP_COPY_USERDATA isn't that deep

[Chris Djali]

Hi,

It's been pointed out to me that the DefaultUserDataContainer object list can be a little bit more deeply copied with this change:


Code:
--- a/src/osg/UserDataContainer.cpp
+++ b/src/osg/UserDataContainer.cpp
@@ -56,7 +56,10 @@ DefaultUserDataContainer::DefaultUserDataContainer(const DefaultUserDataContaine
itr != udc._objectList.end();
++itr)
{
- _objectList.push_back(copyop(itr->get()));
+ if (copyop.getCopyFlags()&osg::CopyOp::DEEP_COPY_USERDATA)
+ _objectList.push_back(osg::clone(itr->get(), copyop));
+ else
+ _objectList.push_back(copyop(itr->get()));
}
}




This will make _objectList at least point to copies of the objects instead of literally the same objects, which is a step in the right direction, but those copies will still be shallow copies.

Cheers,
Chris
