Detailed Description

template<class GFS>
class Dune::PDELab::LocalGlobalMapDataHandle< GFS >

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

fixedsize()

int Dune::CommDataHandleIF< LocalGlobalMapDataHandle< GFS > , int >::fixedsize ( int  dim, int  codim  ) const

inlineinherited

returns true if size of data per entity of given dim and codim is a constant

Parameters

dim	valid dimension (i.e. the grids dimension)
codim	valid codimension of the entity set for which data should be communicated

This method calls 'fixedSize' (with a capital S) of the derived class, if it exists in the derived class. Otherwise, it calls 'fixedsize'.

Deprecated:

This method (with the lower-case 's') is deprecated. Use 'fixedSize' instead!

gather()

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

inlineinherited

pack data from user to message buffer

Parameters

buff	message buffer provided by the grid
e	entity 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

buff	message buffer provided by the grid. This is not const, because the buffer has an internal iterator that gets advanced when reading from the buffer.
e	entity for which date should be unpacked from buffer
n	number 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

e	entity 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.
