Detailed Description
SCBlockInfo contains blocking information for the SCDimension class.
There are really two ways that it can contain blocking information. In the first way, a vector of block offsets and block sizes is stored. The second method is only used by those specializations created by the BlockedSCMatrixKit class. In this method the blocking information is stored as subdimensions of type SCDimension. If both methods are used, they must be used consistently. That is, the number, sizes, and order of the blocks must match the number, sizes, and order of the SCDimension objects.
Constructor & Destructor Documentation
◆ SCBlockInfo()
The KeyVal constructor.
sizesThis is a vector giving the size of each subblock. There is no default.
subdimsIf this vector is given there is must be entry for each entry in the sizes vector. Each entry is an SCDimension object. The default is to not store subdimension information.
Member Function Documentation
◆ save_data_state()
|
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::SavableState.
◆ set_subdim()
| void sc::SCBlockInfo::set_subdim | ( | int | i, |
| const RefSCDimension & | dim | ||
| ) |
Set subdimension information.
The dimension dim and index i must be consistent with the nblocks and blocksizes information given to the constructor.
