From: Wolfgang Bangerth Date: Wed, 2 Sep 2015 19:46:45 +0000 (-0500) Subject: Attempt to disentangle MappingQ1 and MappingQ. X-Git-Tag: v8.4.0-rc2~474^2~11 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a332d1db2803d48c3720c45b63b0bd067138b5f5;p=dealii.git Attempt to disentangle MappingQ1 and MappingQ. Store the polynomial degree in MappingQ1::InternalData, rather than which kind of mapping created it. --- diff --git a/include/deal.II/fe/mapping_q.h b/include/deal.II/fe/mapping_q.h index ec29075344..317eb7953a 100644 --- a/include/deal.II/fe/mapping_q.h +++ b/include/deal.II/fe/mapping_q.h @@ -238,7 +238,7 @@ private: * @{ */ -protected: +public: /** * Storage for internal data of this mapping.
