Member Function Documentation
| void sc::R12IntsAcc_MPIIOFile::commit | ( | ) | [virtual] |
Commit the content of the accumulator for reading - deactivate the associated MemoryGrp and activate the accumulator.
This is a collective operation.
Reimplemented from sc::R12IntsAcc.
| void sc::R12IntsAcc_MPIIOFile::save_data_state | ( | StateOut & | ) | [virtual] |
Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them.
This must be implemented by the derived class if the class has data.
Reimplemented from sc::R12IntsAcc.
Reimplemented in sc::R12IntsAcc_MPIIOFile_Ind.
