Member Function Documentation
◆ fixedsize()
|
inlineinherited |
returns true if size of data per entity of given dim and codim is a constant
- Parameters
-
dim valid dimension (i.e. the grids dimension) codim valid codimension of the entity set for which data should be communicated
This method calls 'fixedSize' (with a capital S) of the derived class, if it exists in the derived class. Otherwise, it calls 'fixedsize'.
- Deprecated:
- This method (with the lower-case 's') is deprecated. Use 'fixedSize' instead!
◆ gather()
|
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()
|
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()
|
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
