Description

template<class Mapper, class Vector>
class Dumux::VectorExchange< Mapper, Vector >

A data handle class to exchange entries of a vector.

Todo:

why is this needed? is parallel/vectorexhange.hh not the same?

Member Function Documentation

contains()

template<class Mapper , class Vector >

bool Dumux::VectorExchange< Mapper, Vector >::contains ( int  dim, int  codim  ) const

inline

returns true if data for this codim should be communicated

fixedsize()

template<class Mapper , class Vector >

bool Dumux::VectorExchange< Mapper, Vector >::fixedsize ( int  dim, int  codim  ) const

inline

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

gather()

template<class Mapper , class Vector >

template<class MessageBuffer , class Entity >

void Dumux::VectorExchange< Mapper, Vector >::gather ( MessageBuffer &  buff, const Entity &  entity  ) const

inline

pack data from user to message buffer

scatter()

template<class Mapper , class Vector >

template<class MessageBuffer , class Entity >

void Dumux::VectorExchange< Mapper, Vector >::scatter ( MessageBuffer &  buff, const Entity &  entity, size_t  n  )

inline

unpack data from message buffer to user

Note

n is the number of objects sent by the sender

size()

template<class Mapper , class Vector >

template<class Entity >

size_t Dumux::VectorExchange< Mapper, Vector >::size ( Entity &  entity ) 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.
