Detailed Description

template<int codim>
class Bempp::EntityIterator< codim >

Abstract base class for iterators over entities.

Parameters

codim

Codimension of the entities iterated over.

Typical usage (here ConcreteEntityIterator is some subclass of EntityIterator<codim>):

ConcreteEntityIterator* it = ...();
while (!it->finished())
{
const ConcreteEntity& e = it.entity();
do_stuff(e);
it->next();
}
delete it;

Member Function Documentation

template<int codim>

virtual std::auto_ptr<EntityPointer<codim> > Bempp::EntityIterator< codim >::frozen ( ) const

pure virtual

A stable pointer to the entity currently referenced by the iterator.

The returned pointer is guaranteed to keep referring to the same entity even if the iterator is incremented or destroyed, as long as the grid is not adapted and the grid object itself stays alive.

Implemented in Bempp::ConcreteSubentityIterator< DuneEntity, codimSub >, and Bempp::ConcreteRangeEntityIterator< DuneEntityIt, DuneEntityPointer >.
