◆ prolongate() [1/2]
Prolongate a vector from level to_level1
to level to_level
using the embedding matrices of the underlying finite element. The previous content of dst
is overwritten.
 Parameters

to_level  The index of the level to prolongate to, which is the level of dst . 
src  is a vector with as many elements as there are degrees of freedom on the coarser level involved. 
dst  has as many elements as there are degrees of freedom on the finer level.

 const

Prolongate a vector from level to_level1
to level to_level
. The previous content of dst
is overwritten.
 src is a vector with as many elements as there are degrees of freedom on the coarser level involved.
 dst has as many elements as there are degrees of freedom on the finer level.

virtualinherited 
Prolongate a vector from level to_level1
to level to_level
, summing into the previous content of dst
.
 src is a vector with as many elements as there are degrees of freedom on the coarser level involved.
 dst has as many elements as there are degrees of freedom on the finer level.
Reimplemented in MGTransferGlobalCoarsening< dim, VectorType >.
Definition at line 47 of file mg_base.cc.
◆ restrict_and_add() [1/2]
Restrict a vector from level from_level
to level from_level1
using the transpose operation of the prolongate() method. If the region covered by cells on level from_level
is smaller than that of level from_level1
(local refinement), then some degrees of freedom in dst
are active and will not be altered. For the other degrees of freedom, the result of the restriction is added.
 Parameters

from_level  The index of the level to restrict from, which is the level of src . 
src  is a vector with as many elements as there are degrees of freedom on the finer level involved. 
dst  has as many elements as there are degrees of freedom on the coarser level.

( 
const unsigned int 
from_level, 


VectorType &

const VectorType &

) 
 const 

pure virtualinherited 
Restrict a vector from level from_level
to level from_level1
and add this restriction to dst
. If the region covered by cells on level from_level
is smaller than that of level from_level1
(local refinement), then some degrees of freedom in dst
are active and will not be altered. For the other degrees of freedom, the result of the restriction is added.
 src is a vector with as many elements as there are degrees of freedom on the finer level
 dst has as many elements as there are degrees of freedom on the coarser level.
Implemented in MGTransferGlobalCoarsening< dim, VectorType >, MGTransferPrebuilt< VectorType >, MGTransferSelect< number >, MGTransferBlockSelect< number >, MGTransferMatrixFree< dim, Number >, MGTransferBlockMatrixFreeBase< dim, Number, TransferType >, MGTransferBlockMatrixFreeBase< dim, Number, MGTransferMatrixFree< dim, Number > >, and MGTransferBlock< number >.
◆ copy_to_mg() [1/2]
Transfer from a blockvector on the global grid to blockvectors defined on each of the levels separately for active degrees of freedom. In particular, for a globally refined mesh only the finest level in dst
is filled as a plain copy of src
. All the other level objects are left untouched.
This function will initialize dst
accordingly if needed as required by the Multigrid class.
◆ copy_to_mg() [2/2]
Same as above for the case that each block has its own DoFHandler.
◆ copy_from_mg() [1/2]
Transfer from multilevel blockvector to normal vector.
◆ copy_from_mg() [2/2]
Same as above for the case that each block has its own DoFHandler.
◆ subscribe()
void Subscriptor::subscribe 
( 
std::atomic< bool > *const 
validity, 


const std::string & 
identifier = "" 

) 
 const 

inherited 
Subscribes a user of the object by storing the pointer validity
. The subscriber may be identified by text supplied as identifier
.
Definition at line 136 of file subscriptor.cc.
◆ unsubscribe()
void Subscriptor::unsubscribe 
( 
std::atomic< bool > *const 
validity, 


const std::string & 
identifier = "" 

) 
 const 

inherited 
Unsubscribes a user from the object.
 Note
 The
identifier
and the validity
pointer must be the same as the one supplied to subscribe().
Definition at line 156 of file subscriptor.cc.
◆ n_subscriptions()
unsigned int Subscriptor::n_subscriptions 
( 
 ) 
const 

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.
◆ list_subscribers() [1/2]
template<typename StreamType >
void Subscriptor::list_subscribers 
( 
StreamType & 
stream  ) 
const 

inlineinherited 
List the subscribers to the input stream
.

const 

inherited 
◆ serialize()
template<class Archive >
void Subscriptor::serialize 
( 
Archive & 
ar, 


const unsigned int 
version 

) 
 

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.
◆ check_no_subscribers()
void Subscriptor::check_no_subscribers 
( 
 ) 
const 

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.
 Note
 Since this function is just a consistency check it does nothing in release mode.

If this function is called when there is an uncaught exception then, rather than aborting, this function prints an error message to the standard error stream and returns.

◆ transfer_operator
template<int dim, typename VectorType >
◆ supports_dof_handler_vector
◆ same_for_all
◆ counter
std::atomic<unsigned int> Subscriptor::counter 

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.
◆ counter_map
std::map<std::string, unsigned int> Subscriptor::counter_map 

mutableprivateinherited 
In this map, we count subscriptions for each different identification string supplied to subscribe().
Definition at line 225 of file subscriptor.h.
◆ validity_pointers
std::vector<std::atomic<bool> *> Subscriptor::validity_pointers 

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.
◆ object_info
const std::type_info* Subscriptor::object_info 

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.
◆ mutex
std::mutex Subscriptor::mutex 

staticprivateinherited 
A mutex used to ensure data consistency when printing out the list of subscribers.
Definition at line 271 of file subscriptor.h.
