bool	contains (int dim, int codim) const
	returns true if data for this codim should be communicated
bool	fixedsize (int dim, int codim) const
	This entire beast is meant for communication like arrays of values at each quadrature point, hence we cannot be fixedsize in the most general case (multiple intersections, different kinds of reference elements).

Detailed Description

template<class IndexSet, class Storage, class Operation>
class Dune::ACFem::IntersectionDataHandle< IndexSet, Storage, Operation >

General intersection - intersection communication which communicates for each intersection a potentially variable number of data-items.

Parameters

IndexSet	The index set for the entities of the underlying GridView.
Storage	A random access container class which allows for indexing with the face index-set. Each element of the container is itself a container with elements which have to be compatible with the Operation functor (i.e. Operation::apply(src, dst) must be possible with the elements of the per-face-entity containers).
Operation	A functor which is called in the scatter() method.

size_t Dune::ACFem::IntersectionDataHandle< IndexSet, Storage, Operation >::size ( EntityType &  e ) const

inline

how many objects of type DataItemType have to be sent for a given entity.

Note: Only the sender side needs to know this size.
