I am storing a std::vector<unsigned int> of size N holding global DOF indices

After doing a SolutionTransfer motivated by AMR, I want to have the new global
DOF indices at the same nodes, so the new vector of indices has the same size N.
I feel the only way to do this is to store the indices along with their
support points before I enter the AMR cycle (so far I only store the indices)
and determine the new indices after refinement by looping over the new mesh
and check the support points for equality.
Is there a more efficient solution for this problem?
Simon,
I think this is the only way to do this. DoF indices are generally not
preserved across mesh refinement.
