Data handle to build up local index to global id and global id to local index map for codim 0 in overlap

Member Function Documentation

◆ gather()

void Dune::CommDataHandleIF< LocalGlobalMapDataHandle< GFS > , int >::gather ( MessageBufferImp &  buff,
const EntityType &  e 
) const
inlineinherited

pack data from user to message buffer

Parameters
buffmessage buffer provided by the grid
eentity for which date should be packed to buffer

◆ scatter() [1/2]

template<class GFS >
template<class MessageBuffer , class EntityType >
void Dune::PDELab::LocalGlobalMapDataHandle< GFS >::scatter ( MessageBuffer &  buff,
const EntityType &  e,
size_t  n 
)
inline

unpack data from message buffer to user

n is the number of objects sent by the sender

◆ scatter() [2/2]

void Dune::CommDataHandleIF< LocalGlobalMapDataHandle< GFS > , int >::scatter ( MessageBufferImp &  buff,
const EntityType &  e,
size_t  n 
)
inlineinherited

unpack data from message buffer to user.

Parameters
buffmessage buffer provided by the grid. This is not const, because the buffer has an internal iterator that gets advanced when reading from the buffer.
eentity for which date should be unpacked from buffer
nnumber of data written to buffer for this entity before

◆ size() [1/2]

size_t Dune::CommDataHandleIF< LocalGlobalMapDataHandle< GFS > , int >::size ( const EntityType &  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.
Parameters
eentity for which the size should be determined

◆ size() [2/2]

template<class GFS >
template<class EntityType >
size_t Dune::PDELab::LocalGlobalMapDataHandle< GFS >::size ( EntityType &  e) const
inline

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

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