DataHandleImp | implementation of the users data handle | |
DataTypeImp | type of data that are going to be communicated which is exported as DataType (for example double) |
Public Types | |
typedef DataTypeImp | DataType |

Public Member Functions | |
bool | contains (int dim, int codim) const |
returns true if data for given valid codim should be communicated | |
bool | fixedsize (int dim, int codim) const |
returns true if size of data per entity of given dim and codim is a constant | |
template<class EntityType> | |
size_t | size (const EntityType &e) const |
how many objects of type DataType have to be sent for a given entity | |
template<class MessageBufferImp, class EntityType> | |
void | gather (MessageBufferImp &buff, const EntityType &e) const |
pack data from user to message buffer | |

bool Dune::CommDataHandleIF< DataHandleImp, DataTypeImp >::contains | ( | int | dim, | |
int | codim | |||
) | const [inline] |
returns true if data for given valid codim should be communicated
dim | valid dimension (i.e. the grids dimension) | |
codim | valid codimension of the entity set for which data should be communicated |
bool Dune::CommDataHandleIF< DataHandleImp, DataTypeImp >::fixedsize | ( | int | dim, | |
int | codim | |||
) | const [inline] |
returns true if size of data per entity of given dim and codim is a constant

unpack data from message buffer to user n is the number of objects sent by the sender
buff | message buffer provided by the grid | |
e | entity for which date should be unpacked from buffer | |
n | number of data written to buffer for this entity before |
