This class provides the mapping information computation and mapping data storage to be used together with FEPointEvaluation.

NonMatching::MappingInfo< dim, spacedim >::MappingInfo | ( | const Mapping< dim > & | mapping, |
const UpdateFlags | update_flags | ||
) |
Constructor.
mapping | The Mapping class describing the geometry of a cell. |
update_flags | Specify the quantities to be computed by the mapping during the call of reinit(). These update flags are also handed to a FEEvaluation object if you construct it with this MappingInfo object. |
Definition at line 137 of file mapping_info.h.
void NonMatching::MappingInfo< dim, spacedim >::reinit | ( | const typename Triangulation< dim, spacedim >::cell_iterator & | cell, |
const ArrayView< const Point< dim >> & | unit_points | ||
) |
Reinitialize the mapping information for the incoming cell and unit points.
Definition at line 158 of file mapping_info.h.
const std::vector< Point< dim > > & NonMatching::MappingInfo< dim, spacedim >::get_unit_points |
Getter function for current unit points.
Definition at line 171 of file mapping_info.h.
const ::internal::FEValuesImplementation::MappingRelatedData< dim, spacedim > & NonMatching::MappingInfo< dim, spacedim >::get_mapping_data |
Getter function for computed mapping data. This function accesses internal data and is therefore not a stable interface.
Definition at line 181 of file mapping_info.h.
const Mapping< dim, spacedim > & NonMatching::MappingInfo< dim, spacedim >::get_mapping |
Getter function for underlying mapping.

UpdateFlags NonMatching::MappingInfo< dim, spacedim >::get_update_flags |
Getter function for the update flags.

Compute the mapping related data for the given mapping

Subscribes a user of the object by storing the pointer validity

Unsubscribes a user from the object.
identifier
and the validity
pointer must be the same as the one supplied to subscribe(). Definition at line 156 of file subscriptor.cc.
|
inlineinherited |
Return the present number of subscriptions to this object. This allows to use this class for reference counted lifetime determination where the last one to unsubscribe also deletes the object.
Definition at line 300 of file subscriptor.h.
|
inlineinherited |
List the subscribers to the input stream
.
Definition at line 317 of file subscriptor.h.

List the subscribers to deallog

Definition at line 204 of file subscriptor.cc.
|
inlineinherited |
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.
|
privatenoexceptinherited |
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.
Definition at line 53 of file subscriptor.cc.

The reference points specified at reinit().
Definition at line 108 of file mapping_info.h.

A pointer to the underlying mapping.
Definition at line 113 of file mapping_info.h.
|

The desired update flags for the evaluation.
Definition at line 118 of file mapping_info.h.
|

The update flags for the desired mapping information.
Definition at line 123 of file mapping_info.h.
|

The internal data container for mapping information. The implementation is subject to future changes.
Definition at line 130 of file mapping_info.h.
|
mutableprivateinherited |
Store the number of objects which subscribed to this object. Initially, this number is zero, and upon destruction it shall be zero again (i.e. all objects which subscribed should have unsubscribed again).
The creator (and owner) of an object is counted in the map below if HE manages to supply identification.
We use the mutable
keyword in order to allow subscription to constant objects also.
This counter may be read from and written to concurrently in multithreaded code: hence we use the std::atomic
class template.
Definition at line 219 of file subscriptor.h.
|
mutableprivateinherited |
In this map, we count subscriptions for each different identification string supplied to subscribe().
Definition at line 225 of file subscriptor.h.
|
mutableprivateinherited |
In this vector, we store pointers to the validity bool in the SmartPointer objects that subscribe to this class.
Definition at line 241 of file subscriptor.h.
|
mutableprivateinherited |
Pointer to the typeinfo object of this object, from which we can later deduce the class name. Since this information on the derived class is neither available in the destructor, nor in the constructor, we obtain it in between and store it here.
Definition at line 249 of file subscriptor.h.

staticprivateinherited |
A mutex used to ensure data consistency when printing out the list of subscribers.
