Detailed Description

template<typename Ordinal, typename T>
class Teuchos::DirectSerializationTraits< Ordinal, T >

Serialization traits for objects that support direct serialization.

"Direct" serialization means that you can convert directly between an object of type T and an array of char, of a specific length dependent only on the type T and not on the particular instance. Specifically, it means you can

reinterpret_cast a pointer to an instance of T into an array of char (which array has length dependent only on the type T and not on the specific T instance),
serialize the resulting array of char, and finally
deserialize by reading in the array of char and doing a reinterpret_cast back into a T.

"Indirect" serialization is defined as any serialization method more general than that.

We use partial specializations of DirectSerializationTraits (specialized on certain T types, not Ordinal) as public base classes for the corresponding SerializationTraits specialization. This provides high-performance default implementations of serialization for commonly used types T (including char, int, and double).

Template Parameters

Ordinal	The same template parameter as that of `Comm`. The integer type used to count the number of packets sent and received.
T	The type of the objects that this class shows how to serialize.
