Typedef Documentation

allocator

template<class type_t>

using xtd::collections::generic::helpers::allocator

#include <xtd.core/include/xtd/collections/generic/helpers/allocator.hpp>

Represent an allocator alias.

Header

#include <xtd/collections/generic/helpers/allocator>

Namespace

xtd::collections::generic::helpers

Library

xtd.core

Remarks

The xtd::collections::generic::helpers::allocator is the default allocator used by all xtd library containers if no user-specified allocator is provided.

The xtd::collections::generic::helpers::allocator is alias on std::allocator.

A simple alias for the moment, which leaves open the possibility of implementing a specific allocator for xtd if necessary in the future.

Examples

The following example show how to use xtd::collections::generic::helpers::allocator with xtd::collections::generic::list.

auto values = xtd::collections::generic::list<date_time, xtd::collections::generic::helpers::allocator<date_time>> {};
values.emplace_back(1971, 1, 5);

iterator_value_t

template<class input_iterator_t>

using xtd::collections::generic::helpers::iterator_value_t

iterator_key_t

template<class input_iterator_t>

using xtd::collections::generic::helpers::iterator_key_t

#include <xtd.core/include/xtd/collections/generic/helpers/iterator.hpp>
