Create an empty striped hash map with the specified maxLoadFactor.

StripedUnorderedContainerImplMaxLoadFactorFlag maxLoadFactorFlag,
float maxLoadFactor = 1.0,
std::size_t numInitialBuckets = k_DEFAULT_NUM_BUCKETS,
std::size_t numStripes = k_DEFAULT_NUM_STRIPES,
bslma::Allocator* basicAllocator = 0);The behavior is undefined unless maxLoadFactor > 0. Optionally specify numInitialBuckets and numStripes which define the minimum number of buckets and the (fixed) number of stripes in this map. Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used. The hash map has rehash enabled.
| Name | Description |
|---|---|
| maxLoadFactorFlag | constructor tag selecting this overload |
| maxLoadFactor | maximum ratio of elements to buckets |
| numInitialBuckets | initial number of buckets |
| numStripes | fixed number of stripes |
| basicAllocator | allocator used to supply memory |
