This class provides the mapping information computation and mapping data storage to be used together with FEPointEvaluation.
MappingInfo is vectorized across quadrature points, which means data can be provided in vectorized format.
Two different modes are available: partially vectorized and fully vectorized across quadrature points. Partially vectorized (scalar Number template argument) means the computed mapping data is provided in scalar format and only unit points are provided vectorized (for seamless interaction with FEPointEvaluation). Fully vectorized (vectorized Number template argument, e.g. VectorizedArray<double>) provides both mapping data and unit points in vectorized format. The Number template parameter of MappingInfo and FEPointEvaluation has to be identical.

Read or write the data of this object to or from a stream for the purpose of serialization using the BOOST serialization library.
This function does not actually serialize any of the member variables of this class. The reason is that what this class stores is only who subscribes to this object, but who does so at the time of storing the contents of this object does not necessarily have anything to do with who subscribes to the object when it is restored. Consequently, we do not want to overwrite the subscribers at the time of restoring, and then there is no reason to write the subscribers out in the first place.
Definition at line 309 of file subscriptor.h.

Check that there are no objects subscribing to this object. If this check passes then it is safe to destroy the current object. It this check fails then this function will either abort or print an error message to deallog (by using the AssertNothrow mechanism), but will not throw an exception.

We use the mutable
