A local integrator object, which can be used to simplify the call of loop(). Instead of providing the three local integration functions separately, we bundle them as virtual functions in this class.
Additionally, since we cannot have a virtual null function, we provide flags, which allow us to indicate, whether we want to integrate on boundary and interior faces. These flags are true by default, but can be modified by applications to speed up the loop.
If a function is not overloaded in a derived class, but its usage flag is true, the function will cause an exception ExcPureFunction.

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.

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.

Subscribes a user of the object by storing the pointer validity

and the validity
pointer must be the same as the one supplied to subscribe(). Definition at line 152 of file enable_observer_pointer.cc.

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 54 of file enable_observer_pointer.cc.
bool MeshWorker::LocalIntegrator< dim, spacedim, number >::use_cell |
The flag indicating whether the cell integrator cell() is to be used in the loop. Defaults to true
.
Definition at line 107 of file local_integrator.h.
bool MeshWorker::LocalIntegrator< dim, spacedim, number >::use_boundary |
The flag indicating whether the boundary integrator boundary() is to be used in the loop. Defaults to true
.
Definition at line 113 of file local_integrator.h.
bool MeshWorker::LocalIntegrator< dim, spacedim, number >::use_face |
The flag indicating whether the interior face integrator face() is to be used in the loop. Defaults to true
.
Definition at line 119 of file local_integrator.h.
std::vector<std::string> MeshWorker::LocalIntegrator< dim, spacedim, number >::input_vector_names |
The names of the input vectors. If this vector is nonempty, it can be used by application programs to automatically select and verify the input vectors used for integration.
Definition at line 133 of file local_integrator.h.
std::vector<std::string> MeshWorker::LocalIntegrator< dim, spacedim, number >::output_names |
The names of the results produced. If this vector is nonempty, it can be used by application programs to automatically assign names to output values and/or verify the names of vectors.

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.

mutableprivateinherited |
In this map, we count subscriptions for each different identification string supplied to subscribe().
Definition at line 218 of file enable_observer_pointer.h.

mutableprivateinherited |
In this vector, we store pointers to the validity bool in the ObserverPointer objects that subscribe to this class.
Definition at line 234 of file enable_observer_pointer.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 242 of file enable_observer_pointer.h.

staticprivateinherited |
A mutex used to ensure data consistency when accessing the mutable
members of this class. This lock is used in the subscribe() and unsubscribe() functions, as well as in list_subscribers()
