Dune::Fem::DataCollector< GridType, LocalDataCollectImp > Class Template Reference

The DataCollector is an example for a grid walk done while load balancing moves entities from one processor to another. The Communicator or grid should call the inlineData (write Data to ObjectStream) and the xtractData (read Data from Stream) and provide the macro level Entity<codim =0> and the ObjectStream. This Operator then does the hierarhic walk and calls its local pack operators which know the discrete functions to pack to the stream. More...

Detailed Description

template<class GridType, class LocalDataCollectImp>
class Dune::Fem::DataCollector< GridType, LocalDataCollectImp >

The DataCollector is an example for a grid walk done while load balancing moves entities from one processor to another. The Communicator or grid should call the inlineData (write Data to ObjectStream) and the xtractData (read Data from Stream) and provide the macro level Entity<codim =0> and the ObjectStream. This Operator then does the hierarhic walk and calls its local pack operators which know the discrete functions to pack to the stream.

apply()

template<class GridType , class LocalDataCollectImp >

void Dune::Fem::DataCollector< GridType, LocalDataCollectImp >::apply ( ObjectStreamType &  str, const EntityType &  entity  ) const

inlinevirtual

apply, if this operator is in write status the inlineData is called else xtractData is called

Reimplemented from Dune::Fem::DataCollectorInterface< GridType, LocalDataCollectImp ::ObjectStreamType >.

saveObjPointer()

template<class DiscrOpType , class LocalOpType >

void Dune::Fem::ObjPointerStorage::saveObjPointer ( DiscrOpType *  discrOp, LocalOpType *  lop  )

inlineinherited

Store new generated DiscreteOperator Pointer and the LocalOperator pointer
