Detailed Description

template<class DiscreteFunctionSpace, class DiscreteFunction, class Operation>
class Dune::Fem::DefaultCommunicationHandlerImpl< DiscreteFunctionSpace, DiscreteFunction, Operation >

Default communication handler for discrete functions.

Parameters

DiscreteFunction

type of discrete function to be communicated

Template Parameters

DiscreteFunction	type of discrete function to be communicated
Operation

Member Function Documentation

gather()

void Dune::CommDataHandleIF< DefaultCommunicationHandlerImpl< DiscreteFunctionSpace, DiscreteFunction, Operation > , DiscreteFunction::DofType >::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()

void Dune::CommDataHandleIF< DefaultCommunicationHandlerImpl< DiscreteFunctionSpace, DiscreteFunction, Operation > , DiscreteFunction::DofType >::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()

size_t Dune::CommDataHandleIF< DefaultCommunicationHandlerImpl< DiscreteFunctionSpace, DiscreteFunction, Operation > , DiscreteFunction::DofType >::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
