Detailed Description

template<typename T>
struct fpmas::communication::TypedMpi< T >

The default fpmas::communication::detail::TypedMpi specialization, based on io::datapack::ObjectPack.

Since ObjectPack serialization rules are predefined for fundamental types and std containers, sending such structure through MPI is made trivial, without any additionnal user defined code:

// Used to transmit integers: predefined
TypedMpi<int> int_mpi;
// Used to transmit vectors of integers: predefined
TypedMpi<std::vector<int>> int_vector_mpi;

If a CustomType is serializable in an ObjectPack, containers of this type can trivially be transmitted, without any additionnal code:

TypedMpi<std::vector<CustomType>> custom_type_vector_mpi;

Template Parameters

T	type to transmit, serializable into an fpmas::io::datapack::ObjectPack
