Detailed Description

template<class T>
struct Foam::UPstream_alias_dataType< T >

Explicit handling of data type aliases. This is necessary since different systems map things like 'unsigned long' differently but we restrict ourselves to int32/int64 types.

Note that this trait serves as the single pass-through point when needing to reference UPstream_mpi_dataType elsewhere
