- the iterator/const_iterator now skip any nullptr entries,
which enables the following code to work even if the PtrList
contains nullptr:
for (const auto& intf : interfaces)
{
// Do something
...
}
- this is a change in behaviour compared to OpenFOAM-v2212 and earlier,
but is non-breaking:
* Lists without null entries will traverse exactly as before.
* Lists with null entries will now traverse correctly without
provoking a FatalError.
