Subject: Introduce type trait is_serial_vector<VectorType>
X-Git-Tag: v8.5.0-rc1~182^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F3784%2Fhead;p=dealii.git

Introduce type trait is_serial_vector<VectorType>

renames type trait is_non_distributed_vector to is_serial_vector and put it into dealii::std_cxx11 namespace

intendation with astyle 2.04 / script

more obivious logical statements as requested

moves true_type and false_type to dealii/base/std_cxx11/type_traits.h

moves specialization of is_serial_vector for dealii::Vector classes to their implementation

correction of implementation

moves vector type traits from a single file to their declaration files

testsuite for vector_type_traits.h for current vectors and instanciations

change request for comments

declares the is_serial_vector template without defining it and minor work on documentation

squashes test cases for is_serial_vector and marks output files for trilinos, petsc, mpi

corrects output files for testsuite (results are correct)

corrects intendation

intendation of #include
