BloombergLP::bdlcc::StripedUnorderedContainerImpl::StripedUnorderedContainerImpl

Create an empty striped hash map with the specified maxLoadFactor.

Synopsis

Declared in <bdlcc_stripedunorderedcontainerimpl.h>

explicit
StripedUnorderedContainerImpl(
    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);

Description

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.

Parameters

Name

Description

maxLoadFactorFlag

constructor tag selecting this overload

maxLoadFactor

numInitialBuckets

initial number of buckets

numStripes

fixed number of stripes

basicAllocator

allocator used to supply memory
