boost::mpi::packed_oarchive — An archive that unpacks binary data from an MPI buffer.

Synopsis

class packed_oarchive {
public:
  // construct/copy/destruct
  packed_oarchive(MPI_Comm const &, buffer_type &, 
                  unsigned int = boost::archive::no_header);
  packed_oarchive(MPI_Comm const &, unsigned int = boost::archive::no_header);

  // public member functions
  template<typename T> void save_override(T const &, int, mpl::false_) ;
  template<typename T> void save_override(T const &, int, mpl::true_) ;
  template<typename T> void save_override(T const &, int) ;
};

Description

The packed_oarchive class is an Archiver (as in the Boost.Serialization library) that unpacks binary data from a buffer received via MPI. It can operate on any Serializable data type and will use the MPI_Unpack function of the underlying MPI implementation to perform deserialization.

`packed_oarchive` public construct/copy/destruct

packed_oarchive(MPI_Comm const & comm, buffer_type & b, 
                unsigned int flags = boost::archive::no_header);

Construct a packed_oarchive to receive data over the given MPI communicator and with an initial buffer.

Parameters:

`b`	A user-defined buffer that contains the binary representation of serialized objects.
`comm`	The communicator over which this archive will be received.
`flags`	Control the serialization of the data types. Refer to the Boost.Serialization documentation before changing the default flags.

packed_oarchive(MPI_Comm const & comm, 
                unsigned int flags = boost::archive::no_header);

Construct a packed_oarchive to receive data over the given MPI communicator.

Parameters:

`comm`	The communicator over which this archive will be received.
`flags`	Control the serialization of the data types. Refer to the Boost.Serialization documentation before changing the default flags.
