Member Function Documentation
◆ contains()
template<typename GFS , typename V , typename GatherScatter , typename CommunicationDescriptor = DOFDataCommunicationDescriptor<typename V::ElementType>>
|
inline |
returns true if data for this codim should be communicated
◆ fixedsize()
template<typename GFS , typename V , typename GatherScatter , typename CommunicationDescriptor = DOFDataCommunicationDescriptor<typename V::ElementType>>
|
inline |
returns true if size per entity of given dim and codim is a constant
◆ gather() [1/2]
template<typename GFS , typename V , typename GatherScatter , typename CommunicationDescriptor = DOFDataCommunicationDescriptor<typename V::ElementType>>
template<typename MessageBuffer , typename Entity >
|
inline |
pack data from user to message buffer - version with support for sending leaf ordering sizes
◆ gather() [2/2]
template<typename GFS , typename V , typename GatherScatter , typename CommunicationDescriptor = DOFDataCommunicationDescriptor<typename V::ElementType>>
template<typename MessageBuffer , typename Entity >
|
inline |
pack data from user to message buffer - version without support for sending leaf ordering sizes
◆ scatter() [1/2]
template<typename GFS , typename V , typename GatherScatter , typename CommunicationDescriptor = DOFDataCommunicationDescriptor<typename V::ElementType>>
template<typename MessageBuffer , typename Entity >
|
inline |
unpack data from message buffer to user
n is the number of objects sent by the sender
This is the version with support for receiving leaf ordering sizes
◆ scatter() [2/2]
template<typename GFS , typename V , typename GatherScatter , typename CommunicationDescriptor = DOFDataCommunicationDescriptor<typename V::ElementType>>
template<typename MessageBuffer , typename Entity >
|
inline |
unpack data from message buffer to user
n is the number of objects sent by the sender
This is the version without support for receiving leaf ordering sizes
◆ size()
template<typename GFS , typename V , typename GatherScatter , typename CommunicationDescriptor = DOFDataCommunicationDescriptor<typename V::ElementType>>
template<typename Entity >
|
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.
