Member Function Documentation

◆ 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.
