hash_multimap::hash_multimap

Note

This API is obsolete. The alternative is unordered_multimap Class.

Constructs a hash_multimap that is empty or is a copy of all or part of some other hash_multimap.

hash_multimap( );
explicit hash_multimap(
    const Compare& Comp
);
hash_multimap(
    const Compare& Comp,
    const Allocator& Al
);
hash_multimap(
    const hash_multimap& Right
);
hash_multimap(
    hash_multimap&& Right
);
hash_multimap(
    initializer_list<Type> IList
);
hash_multimap(
    initializer_list<Type> IList,
    const Compare& Comp
);

hash_multimap(
    initializer_list<Type> IList,
    const Compare& Comp,
    const Allocator& Al
);
template<class InputIterator>
    hash_multimap(
        InputIterator First,
        InputIterator Last
    );
template<class InputIterator>
    hash_multimap(
        InputIterator First,
        InputIterator Last,
        const Compare& Comp
    );
template<class InputIterator>
    hash_multimap(
        InputIterator First,
        InputIterator Last,
        const Compare& Comp,
        const Allocator& Al
    );

Parameters

Parameter

Description

Al

The storage allocator class to be used for this hash_multimap object, which defaults to Allocator.

Comp

The comparison function of type constTraits used to order the elements in the map, which defaults to Traits.

Right

The map of which the constructed set is to be a copy.

First

The position of the first element in the range of elements to be copied.

Last

The position of the first element beyond the range of elements to be copied.

IList

The initializer_list to copy from.

Remarks

All constructors store a type of allocator object that manages memory storage for the hash_multimap and that can later be returned by calling get_allocator. The allocator parameter is often omitted in the class declarations and preprocessing macros are used to substitute alternative allocators.

All constructors initialize their hash_multimap.

All constructors store a function object of type Traits that is used to establish an order among the keys of the hash_multimap and can later be returned by calling key_comp.

The first three constructors specify an empty initial hash_multimap; the second specifies the type of comparison function (Comp) to be used in establishing the order of the elements and the third explicitly specifies the allocator type (_Al) to be used. The keyword explicit suppresses certain kinds of automatic type conversion.

The fourth constructor specifies a copy of the hash_multimap Right.

The next three constructors copy the range First, Last) of a map with increasing explicitness in specifying the type of comparison function of class Traits and allocator.

The eighth constructor moves the hash_multimap Right.

The final three constructors use an initializer_list.
