class MGTransferBlockMF< dim, Number >
This class works with LinearAlgebra::distributed::BlockVector and performs exactly the same transfer operations for each block as MGTransferMF.

◆ prolongate()
Prolongate a vector from level to_level-1
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. |
Implements MGTransferBase< LinearAlgebra::distributed::BlockVector< Number > >.
◆ prolongate_and_add()
Prolongate a vector from level to_level-1
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 from MGTransferBase< LinearAlgebra::distributed::BlockVector< Number > >.
◆ restrict_and_add()
Restrict a vector from level from_level
to level from_level-1
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_level-1
(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. |
Implements MGTransferBase< LinearAlgebra::distributed::BlockVector< Number > >.
◆ copy_to_mg() [1/2]
Transfer from a block-vector on the global grid to block-vectors 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 multi-level block-vector to normal vector.
◆ copy_from_mg() [2/2]
Same as above for the case that each block has its own DoFHandler.

( |
std::atomic< bool > *const |
validity, |

const std::string & |

| const |

Subscribes a user of the object by storing the pointer validity
. The subscriber may be identified by text supplied as identifier
.

◆ n_subscriptions()
unsigned int EnableObserverPointer::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.

| |
|
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 331 of file enable_observer_pointer.h.
◆ check_no_subscribers()
void EnableObserverPointer::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.

◆ counter
std::atomic<unsigned int> EnableObserverPointer::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.

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.
