Syntax

template<typename ValueType, typename CountType, class SortKeyClass>
void RadixSort32
(
    ValueType *restrict Dst,
    ValueType *restrict Src,
    CountType Num,
    SortKeyClass SortKey
)

Remarks

Very fast 32bit radix sort. SortKeyClass defines operator() that takes ValueType and returns a uint32. Sorting based on key. No comparisons. Is stable. Use a smaller CountType for smaller histograms.
