Serialization of std::shared_ptr

std::shared_ptr are normally supported out-of-the-box (given the underlying type is serializable (similar to Marshalling pointer types (e.g. items which are pointers)).

Only shared_ptrs to more complex pointer-types require special treatment to guarantee correct garbage collection. If

• using std::shared:ptr
• AND the pointer-class holds data which is dynamically allocated
• AND this dynamic memory is NOT allocated in the default constructor but during marshalling with CnC::chunk

then (and only then) you might want to use construct_array and destruct_array. It is probably most convenient to

• use the standard CnC::chunk mechanism during serialization
• allocate dynamic memory in the constructors with construct_array
• and deallocate it in the destructor using destruct_array

This mechanism is used in the cholesky example which comes with this distribution.

Alternatively you can use matching allocation/deallocation explicitly in your con/destructors and during serialization.
