Subject: Improve forward declarations in dof_tools.h.
X-Git-Tag: v8.5.0-rc1~1229^2~10
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=596fa272c8fe055782f9eaa5a11f4fb231d7e307;p=dealii.git

Improve forward declarations in dof_tools.h.

This commit does two things: it brings in hp/dof_handler.h
explicitly (since details of that class are used) and cleans up the
forward declarations already present.
