Member Function Documentation

◆ dataHandleSize()

template<typename GFS >
template<typename Entity >
size_type Dune::PDELab::DataHandleProvider< GFS >::dataHandleSize ( const Entity e) const
inlineinherited

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

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

◆ sendLeafSizes()

template<typename GFS >
constexpr bool Dune::PDELab::DataHandleProvider< GFS >::sendLeafSizes ( ) const
inlineconstexprinherited

Returns true if the sizes of the leaf orderings in this tree should be sent as part of the communcation.

The MultiDomain extensions require knowledge about the size of the individual orderings, which might belong to separate subdomains. Otherwise it is possible to have size mismatches for entities with codim > 0 if there are protruding edges in the parallel mesh partitioning.

By default, this method will always return false. It must be overridden for cases where the data actually needs to be sent.

This flag also modifies the behavior of the generic data handles, which will automatically send, receive and process the additional information. Note that if sendLeafSizes() returns true, the underlying DataHandleIF of the grid will always use the data type char to be able to send different types of data, which will automatically be marshalled to / from a byte stream.
