Interface for objects which are hold inside of document as field values and can serialize yourself into document. In such way it is possible to serialize complex types and do not break compatibility with non-Java binary drivers. After serialization into document additional field {@link #CLASS_NAME} will be added. This field contains value of class oforiginal object. During deserialization of embedded object if embedded document contains {@link #CLASS_NAME} field we try to find class with givenname and only if this class implements {@link ODocumentSerializable} interface it will be converted to the object. So it ispretty safe to use field with {@link #CLASS_NAME} in ordinary documents if it is needed.Class which implements this interface should have public no-arguments constructor. @author Andrey Lomakin Andrey Lomakin @since 3/27/14
