Paras,
I am trying to read a list of integers from the parameter file using the
dealii::Patterns::List class.
However, I get a runtime error which can be reproduced using the attached MWE.
I also tried the approach described (for tensor) in
https://groups.google.com/g/dealii/c/TvtcOnxeVjw/m/9uaSAh-kAwAJ but it doesn't
seem to work for the current case.
It would be great help if someone could help me understand where I go wrong?
First: Excellent job coming up with a self-contained minimal example!
The problem is that in this line:
nIters =
dealii::Patterns::Tools::Convert<decltype(nIters)>::to_value(nMaxItersString);
The to_value() function creates its own pattern based on the type of the
argument nMaxItersString. This pattern uses "," as the separator, but you want
"|". You can fix this by providing an explicit pattern:
nIters =
dealii::Patterns::Tools::Convert<decltype(nIters)>::to_value(nMaxItersString,dealii::Patterns::List(dealii::Patterns::Integer(1),
2, 8, "|"));
Best
W.
