Extended interface of entities of codimension 0 |
template<int cc> |
int | count () const |
| Number of subentities with codimension cc . This method is in principle redundant because this information can be obtained via the reference element of the geometry. It is there for efficiency reasons and to make the interface self-contained.
|
template<int codim> |
Codim< codim >::EntityPointer | subEntity (int i) const |
| obtain a pointer to a subentity
|
LeafIntersectionIterator | ileafbegin () const |
| Access to intersections with neighboring leaf elements. A neighbor is an entity of codimension 0 which has an intersection of codimension 1 in common with this entity. Access to those neighbors is provided using the IntersectionIterator. This method returns an iterator refering to the first neighbor.
|
LeafIntersectionIterator | ileafend () const |
| Reference to an IntersectionIterator one past the last intersection.
|
LevelIntersectionIterator | ilevelbegin () const |
| Intra-level access to intersections with neighboring elements. A neighbor is an entity of codimension 0 which has an intersection of codimension 1 in common with this entity. Access to those neighbors is provided using the IntersectionIterator. This method returns an iterator refering to the first neighbor.
|
LevelIntersectionIterator | ilevelend () const |
| Reference to an IntersectionIterator one past the last intersection.
|
EntityPointer | father () const |
| Inter-level access to father entity on the next-coarser grid. The given entity resulted directly from a subdivision of its father entity. For the macro elements dereferencing the EntityPointer is undefined.
|
bool | hasFather () const |
| Return true if entity has a father entity which can be accessed using the father() method.
|
bool | isLeaf () const |
| Returns true if the entity is contained in the leaf grid.
|
bool | isRegular () const |
| Returns true if element is of regular type in red/green type refinement. In bisection or hanging node refinement this is always true.
|
LocalGeometry | geometryInFather () const |
| Provides information how this element has been subdivided from its father element.
|
HierarchicIterator | hbegin (int maxlevel) const |
| Inter-level access to elements that resulted from (recursive) subdivision of this element.
|
HierarchicIterator | hend (int maxlevel) const |
| Returns iterator to one past the last son element.
|
bool | isNew () const |
| Returns true, if the entity has been created during the last call to adapt()
|
bool | mightVanish () const |
| Returns true, if entity might disappear during the next call to adapt(). If the method returns false, the entity is guaranteed to still be present after adaptation.

The geometry type of this entity when the geometry is expressed embedded in the father element.
This differs from Geometry in particular when dim != dimworld, but even when dim == dimworld the implementation may choose to use a different type here.

- If the partitionType of the Entity is GhostEntity, it is not guaranteed that this method is working or implemented in general. For some grids it might be available, though.

template<int dim, class GridImp , template< int, int, class > class EntityImp>
Provides information how this element has been subdivided from its father element.
The returned LocalGeometry is a model of Dune::Geometry<dimension,dimension,...>, mapping the reference element of the given entity to the reference element of its father.
This information is sufficient to interpolate all degrees of freedom in the conforming case. Nonconforming may require access to neighbors of the father and calculations with local coordinates. The on-the-fly case is somewhat inefficient since degrees of freedom may be visited several times. If we store interpolation matrices, this is tolerable. We assume that on-the-fly implementation of interpolation is only done for simple discretizations.
- Note
- For ghost entities, this method is not guaranteed to be implemented.
-
Previously, the geometry was encapsulated in the entity object and a const reference was returned.
-
The returned geometry object is guaranteed to remain valid until the grid is modified (or deleted).

Inter-level access to elements that resulted from (recursive) subdivision of this element.
- Parameters
-
[in] | maxlevel | Iterator does not stop at elements with level greater than maxlevel. |
- Returns
- Iterator to the first son (level is not greater than maxlevel)

Access to intersections with neighboring leaf elements. A neighbor is an entity of codimension 0 which has an intersection of codimension 1 in common with this entity. Access to those neighbors is provided using the IntersectionIterator. This method returns an iterator refering to the first neighbor.
- Note
- If the partitionType of the Entity is GhostEntity, this method might give you only one neighbor, which is the interior Entity the GhostEntity is connected to.
