Exported types and constants | |
enum | { codimension = 0 } |
enum | { dimension = dim } |
enum | { mydimension = dim } |
enum | { dimensionworld = dimworld } |
typedef GridImp::template Codim< 0 >::Geometry | Geometry |
The geometry type of this entity. | |
typedef GridImp::template Codim< 0 >::LocalGeometry | LocalGeometry |
The geometry type of this entity when the geometry is expressed embedded in the father element. This differs from Geometry only when dim != dimworld. | |
typedef GridImp::template Codim< 0 >::EntityPointer | EntityPointer |
The codim==0 EntityPointer type. | |
typedef GridImp::template Codim< 0 >::LeafIntersectionIterator | LeafIntersectionIterator |
The LeafIntersectionIterator type. | |
typedef GridImp::template Codim< 0 >::LevelIntersectionIterator | LevelIntersectionIterator |
The LevelIntersectionIterator type. | |
typedef GridImp::template Codim< 0 >::HierarchicIterator | HierarchicIterator |
The HierarchicIterator type. | |
typedef ct | ctype |
Type used for coordinates in grid module. | |
Protected methods | |
EntityImp< 0, dim, GridImp > & | getRealImp () |
return reference to the real implementation | |
const EntityImp< 0, dim, GridImp > & | getRealImp () const |
return reference to the real implementation | |
Entity (const Entity &rhs) | |
Entity & | operator= (const Entity &rhs) |
Methods shared by entities of all codimensions | |
int | level () const |
The level of this entity. | |
PartitionType | partitionType () const |
Partition type of this entity. | |
const Geometry & | geometry () const |
Each entity encapsulates an object of type Dune::Geometry<dimension-codimension,dimensionworld,...> that gives (among other things) the map from a reference element to world coordinates. This method delivers a const reference to such a geometry.
| |
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 cc> | |
Codim< cc >::EntityPointer | entity (int i) const |
Access to subentity i of codimension cc . | |
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 | 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. | |
const LocalGeometry & | geometryInFather () const |
Provides information how this element has been subdivided from its father element. The returned LocalGeometry is a model of Dune::Geometry<dimension,dimension,...> mapping from the reference element of the given element to the reference element of the father element. This is sufficient to interpolate all degrees of freedom in the conforming case. Nonconforming may require access to neighbors of father and computations with local coordinates. 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. | |
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 | wasRefined () const |
Returns true, if entity was refined during last adaptation cycle. | |
bool | mightBeCoarsened () const |
Returns true, if entity might be coarsened during next adaption cycle. | |
Interface for the implementor | |
bool | hasBoundaryIntersections () const |
Returns true, if entity has intersections with boundary, see default implementation. | |
Entity (const EntityImp< 0, dim, GridImp > &e) | |
Copy constructor from EntityImp. | |
Public Member Functions | |
GeometryType | type () const |
Return the name of the reference element. The type can be used to access the Dune::ReferenceElement. | |
