STYLE: Replace index.Fill with auto index = Index::Filled in tests

N-Dekker · N-Dekker · commit e991e270c0c2 · 2024-10-19T22:16:23.000+02:00
Replaced code of the form IndexType index; index.Fill(x); with `auto index = IndexType::Filled(x);` Following C++ Core Guidelines, Oct 3, 2024, "Always initialize an object", https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Res-always Using Notepad++, Replace in Files, doing: Find what: ^([ ]+ )(.*::Index.*[^ ])[ ]+(\w+);[\r\n]+ [ ]+\3\.Fill\( Find what: ^([ ]+ )(IndexType)[ ]+(\w+);[\r\n]+ [ ]+\3\.Fill\( Replace with: $1auto $3 = $2::Filled\( Filters: itk*Test*.cxx [v] Match case (*) Regular expression Removed "typename" keywords from `typename T::::IndexType::Filled` calls. Follow-up to pull request #4881 commit 569a8b6 "STYLE: Replace Fill(0) with {} initializer for local variables in tests"
