[osg-users] DEEP_COPY_USERDATA isn't that deep

[Chris Djali]

Hi,

Is it intentional that using osg::CopyOp::DEEP_COPY_USERDATA copies the UserDataContainer, but doesn't deep-copy the actual things in it unless osg::CopyOp::DEEP_COPY_OBJECTS is also enabled? This means that things can be added or removed, but changes to existing things are shared.

We have a situation where we only want to deep-copy the userdata and not anything else, so can't set the deep-copy objects flag. This could be supported either by ORing objects into the copy op in the userdata container copy constructor, or by adding another copy op for copying userdata even more deeply, otherwise we're going to have to manually implement a less pretty workaround.

Cheers,
Chris
