BloombergLP::bslstl::HashTableIterator

STL‐conforming forward iterator over hash‐table node lists.

Synopsis

Declared in <bslstl_hashtableiterator.h>

template<
    class VALUE_TYPE,
    class DIFFERENCE_TYPE>
class HashTableIterator;

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. A HashTableIterator object provides access to values of the (template parameter) VALUE_TYPE, stored in a hash table composed of bslalg::BidirectionalLink nodes. The (template parameter) DIFFERENCE_TYPE determines the standard mandated difference_type of the iterator, without requiring access to the allocator‐traits for the node.
