MGLevelObject< LinearOperator< VectorType > > | matrices |
Multilevel matrix. This matrix stores an MGLevelObject of LinearOperator objects. It implements the interface defined in MGMatrixBase, so that it can be used as a matrix in Multigrid.
Definition at line 44 of file mg_matrix.h.

default |
Default constructor for an empty object.
|
inline |
Constructor setting up pointers to the matrices in M
by calling initialize().
Definition at line 230 of file mg_matrix.h.
|
inline |
Initialize the object such that the level multiplication uses the matrices in M
Definition at line 202 of file mg_matrix.h.
|
inline |
Reset the object.

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

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 301 of file subscriptor.h.
|
inlineinherited |
List the subscribers to the input stream
.

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.
