Dereferencing
Entity &	operator* () const
	Dereferencing operator.
Entity *	operator-> () const
	Pointer operator.
Compare methods
bool	operator== (const EntityPointer< GridImp, ItImp > &rhs) const
	Checks for equality. Only works for EntityPointers and iterators on the same grid. Due to the conversion operators one can compare all kinds of iterators and EntityPointer.
bool	operator!= (const EntityPointer< GridImp, ItImp > &rhs) const
	Checks for inequality. Only works for EntityPointers and iterators on the same grid. Due to the conversion operators one can compare all kinds of iterators and EntityPointer.
Query methods
int	level () const
	Ask for level of entity. This method is redundant and is only there for efficiency reasons. It allows an implementation to return the level without actually constructing the entity.
Implementor interface
bool	equals (const EntityPointer< GridImp, ItImp > &rhs) const
	Forward equality check to realIterator.

Protected Member Functions

	return reference to the real implementation

Detailed Description

template<class GridImp, template< class > class HierarchicIteratorImp>
class Dune::HierarchicIterator< GridImp, HierarchicIteratorImp >

Enables iteration over all codim zero entities in a subtree See also the documentation of Dune::EntityPointer.

Mesh entities of codimension 0 ("elements") allow to visit all entities of codimension 0 obtained through nested, hierarchic refinement of the entity. Iteration over this set of entities is provided by the HierarchicIterator, starting from a given entity. This is redundant but important for memory efficient implementations of unstructured hierarchically refined meshes.

Note

The HierarchicIterator interface is deprecated. Use the EntityIterator interface instead.
