X-Git-Tag: v9.0.0-rc1~1437^2 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c09950ca5588831102f9d8d7250554d314c3d749;p=dealii.git de-templatize SparsityPattern::copy_from. This template is instantiated for only SparsityPattern and is overloaded for DynamicSparsityPattern, so it is a bit simpler to just overload a non-template method. --- diff --git a/include/deal.II/lac/sparsity_pattern.h b/include/deal.II/lac/sparsity_pattern.h index 369a58c554..f6f6f53b04 100644 --- a/include/deal.II/lac/sparsity_pattern.h +++ b/include/deal.II/lac/sparsity_pattern.h @@ -38,6 +38,7 @@ DEAL_II_NAMESPACE_OPEN class SparsityPattern; +class DynamicSparsityPattern; class ChunkSparsityPattern; template class FullMatrix; template class SparseMatrix; @@ -630,15 +631,16 @@ public: const ForwardIterator end); /** - * Copy data from an object of type DynamicSparsityPattern.
