AthLinks+AthContainersInterfaces: use explicit type casts
I recently tried to compile some xAOD EDM packages with -Wconversion
for code quality purposes. To reduce the "noise" a bit, this MR introduces a few explicit static_cast
s in the header files to fix -Wconversion
related warnings.
We would never want to compile the full release with these warnings enabled, but it can be useful during the development process.
