X-Git-Tag: v8.3.0-rc1~71^2 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=28d8f3cb4107242efe489212776a290a3b0a4341;p=dealii.git Add a declared but not implemented function. This addresses a linker error recently posted to the mailing list. The issue is that we have iterators that represent faces of cells and a specialization for the faces of 1d cells, i.e., vertices. These class specializations have most of the regular accessor members declared, but here is one that was declared without being defined. This patch adds a definition of the function. The issue is relatively uncritical since the so-defined function does not actually have to do anything other than return an invalid object (vertices have no children). --- diff --git a/doc/news/changes.h b/doc/news/changes.h index 8f0c051b50..b1dc8ddad2 100644 --- a/doc/news/changes.h +++ b/doc/news/changes.h @@ -532,6 +532,14 @@ inconvenience this causes.

Specific improvements

    +
  1. Fixed: The specialization of DoFAccessor for zero-dimensional objects, + i.e., for vertices as created by accessing the faces of one-dimensional + cells, had a member function DoFAccessor::child() that was declared but not + implemented. This is now fixed. +

  2. +
  3. Improved: Functions::Monomial::gradient function now works when both base and exponent are equal to zero for one or more components of the monomial. Also, an assertion is added to avoid exponentiation of negative base numbers with real exponents. diff --git a/include/deal.II/dofs/dof_accessor.h b/include/deal.II/dofs/dof_accessor.h index 89b7cf4e28..89ee601037 100644 --- a/include/deal.II/dofs/dof_accessor.h +++ b/include/deal.II/dofs/dof_accessor.h @@ -294,7 +294,7 @@ public: */ /** - * Return an iterator pointing to the the @p c-th child. + * Return an iterator pointing to the @p c-th child. */ TriaIterator > child (const unsigned int c) const; @@ -798,7 +798,9 @@ public: */ /** - * Return an iterator pointing to the the @p c-th child. + * Return an invalid iterator of a type that represents pointing to a child + * of the current object.
