contains()

template<class Mapper , class Vector , int entityCodim, class ScatterOperator , class DataT = typename Vector::value_type>

bool Dumux::VectorCommDataHandle< Mapper, Vector, entityCodim, ScatterOperator, DataT >::contains ( int  dim, int  codim  ) const

inline

returns true if data for this codim should be communicated

fixedSize()

template<class Mapper , class Vector , int entityCodim, class ScatterOperator , class DataT = typename Vector::value_type>

bool Dumux::VectorCommDataHandle< Mapper, Vector, entityCodim, ScatterOperator, DataT >::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 , int entityCodim, class ScatterOperator , class DataT = typename Vector::value_type>

template<class MessageBuffer , class Entity >

void Dumux::VectorCommDataHandle< Mapper, Vector, entityCodim, ScatterOperator, DataT >::gather ( MessageBuffer &  buff, const Entity &  entity  ) const

inline

pack data from user to message buffer

scatter()

template<class Mapper , class Vector , int entityCodim, class ScatterOperator , class DataT = typename Vector::value_type>

template<class MessageBuffer , class Entity >

void Dumux::VectorCommDataHandle< Mapper, Vector, entityCodim, ScatterOperator, DataT >::scatter ( MessageBuffer &  buff, const Entity &  entity, std::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 , int entityCodim, class ScatterOperator , class DataT = typename Vector::value_type>

template<class Entity >

std::size_t Dumux::VectorCommDataHandle< Mapper, Vector, entityCodim, ScatterOperator, DataT >::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.
