BloombergLP::bslstl::HashTableBucketIterator

Standard‐conforming forward iterator over a single hash‐table bucket.

Synopsis

Declared in <bslstl_hashtablebucketiterator.h>

template<
    class VALUE_TYPE,
    class DIFFERENCE_TYPE>
class HashTableBucketIterator;

Description

This class template implements an in‐core value‐semantic type that is an standard‐conforming forward iterator (see section 24.2.5 [forward.iterators]of the C++11 standard) over a list of bslalg::BidirectionalLink objects referred to by a single bslalg::HashTableBucket object. A HashTableBucketIterator object provides access to values of the (template parameter) VALUE_TYPE, stored in a bucket of a hash table. The (template parameter) DIFFERENCE_TYPE determines the standard mandated difference_type of the iterator, without requiring access to the allocator‐traits for the node.
