- single() method : simply tests if the globalIndex has nProcs == 1,
which is typically from a gatherNone invocation.
For example,
globalIndex gi;
if (...) gi.reset(localSize);
else gi.reset(globalIndex::gatherNone{}, localSize);
// later...
const label begin = (gi.single() ? 0 : gi.localStart());
const label count = (gi.single() ? gi.totalSize() : gi.localSize());
- add front() and back() methods to return the begin/end ranges,
and begin_value(), end_value() - as per labelRange.
- make more methods noexcept
- calcOffset(), calcRange() helper functions to determine
the processor-local of a numbering range without the overhead of
creating a list of offsets.
For example,
label myOffset = globalIndex::calcOffset(mesh.nCells());
labelRange mySlice = globalIndex::calcRange(mesh.nCells());
- add globalIndex localEnd() as per CompactListList method
STYLE: align looping constructs in CompactListList with List
- make more methods noexcept
