Introduces a pure virtual method responsible for writing to a mxArray
Matlab object, typically a MATLAB struct
whose contents are documented in each derived class.
mxArray
(caller is responsible of memory freeing) or NULL is class does not support conversion to MATLAB. Definition at line 79 of file CSerializable.h.

Introduces a pure virtual method responsible for writing to a CStream.
This can not be used directly be users, instead use "stream << object;" for writing it to a stream.
out | The output binary stream where object must be dumped. |
getVersion | If NULL, the object must be dumped. If not, only the version of the object dump must be returned in this pointer. This enables the versioning of objects dumping and backward compatibility with previously stored data. |
std::exception | On any error, see CStream::WriteBuffer |
Implements mrpt::utils::CSerializable.
