BloombergLP::bslstl::HashTableIterator

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.

Type Aliases

Name	Description
`difference_type`	Iterator difference type.
`iterator_category`	Standard iterator defined types [24.4.2].
`pointer`	This `typedef` is an alias to `VALUE_TYPE *`.
`reference`	This `typedef` is an alias to `VALUE_TYPE&`.
`value_type`	This `typedef` is an alias to the non-`const` form of `VALUE_TYPE`.
