From c0e3eff5b7240e8e11ac5a4f992f91ba62e85476 Mon Sep 17 00:00:00 2001 From: Ralf Hartmann Date: Wed, 19 May 2004 09:41:01 +0000 Subject: [PATCH] New MGLevelObject & operator = (const double d) function to distinguish from the clear function which now (as in the past) calles clear on each element of the MGLevelObject class. git-svn-id: https://svn.dealii.org/trunk@9267 0785d39b-7218-0410-832d-ea1e28bc413d --- .../include/multigrid/mg_level_object.h | 34 +++++++++++++------ 1 file changed, 23 insertions(+), 11 deletions(-) diff --git a/deal.II/deal.II/include/multigrid/mg_level_object.h b/deal.II/deal.II/include/multigrid/mg_level_object.h index 4b643df2d3..b721513f71 100644 --- a/deal.II/deal.II/include/multigrid/mg_level_object.h +++ b/deal.II/deal.II/include/multigrid/mg_level_object.h @@ -65,22 +65,23 @@ class MGLevelObject : public Subscriptor */ void resize (const unsigned int new_minlevel, const unsigned int new_maxlevel); + + /** + * Call operator = (s) + * on all objects stored by this + * object.
