/** |
|
* @brief Register the type T for direct serialization within Boost.MPI |
|
* |
|
* The @c register_serialized function registers a C++ type for direct |
|
* serialization within Boost.MPI. Direct serialization elides the use |
|
* of the Python @c pickle package when serializing Python objects |
|
* that represent C++ values. Direct serialization can be beneficial |
|
* both to improve serialization performance (Python pickling can be |
|
* very inefficient) and to permit serialization for Python-wrapped |
|
* C++ objects that do not support pickling. |
|
* |
|
* @param value A sample value of the type @c T. This may be used |
|
* to compute the Python type associated with the C++ type @c T. |
|
* |
|
* @param type The Python type associated with the C++ type @c |
|
* T. If not provided, it will be computed from the same value @p |
|
* value. |

* @brief Registers a type for use with the skeleton/content mechanism |

* |
|
* The skeleton/content mechanism can only be used from Python with |
|
* C++ types that have previously been registered via a call to this |
|
* function. Both the sender and the transmitter must register the |
|
* type. It is permitted to call this function multiple times for the |
|
* same type @c T, but only one call per process per type is |
|
* required. The type @c T must be Serializable. |
|
* |
|
* @param value A sample object of type T that will be used to |
|
* determine the Python type associated with T, if @p type is not |
|
* specified. |
