std::vector<double> anonymous_namespace{OverlapsJoinHashTable.cpp}::BucketSizeTuner::getInverseBucketSizes()

Method to retrieve inverted bucket sizes, which are what are used elsewhere in the OverlapsHashTable framework

Return

the inverted bucket sizes, i.e. a set of that will place a raw value in a bucket when multiplied by the raw value
