Declared in <bdlcc_stripedunorderedcontainerimpl.h>

Create an empty StripedUnorderedContainerImpl object, a fully thread‐safe hash map where access is divided into "stripes" (a group of buckets protected by a reader‐write mutex). 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.

explicit
StripedUnorderedContainerImpl(
    std::size_t numInitialBuckets = k_DEFAULT_NUM_BUCKETS,
    std::size_t numStripes = k_DEFAULT_NUM_STRIPES,
    bslma::Allocator* basicAllocator = 0);

Create an empty StripedUnorderedContainerImpl object, a fully thread‐safe hash map where access is divided into "stripes" (a group of buckets protected by a reader‐write mutex). Specify maxLoadFactor which defines the maximum ratio of elements to buckets. 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.
