Subject: Use std::unique_ptr instead of std::shared_ptr for DoFHandler::policy.
X-Git-Tag: v9.0.0-rc1~1487^2~14
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e1ae97ee2d157120d1f94899c268910a96eff7a8;p=dealii.git

Use std::unique_ptr instead of std::shared_ptr for DoFHandler::policy.

This is possible because DoFHandler has no copy constructor or operator, and consequently
there is no reason to share a policy.
