	Implements a function object for compare data. More...
struct	xtd::collections::generic::helpers::equator< key_t >
	Implements a function object for performing comparisons. Unless specialised, invokes operator== on type type_t. xtd::equator with the key and the value strongly typed to be std::any. More...

	Implements a function object for hashing data. More...

Typedefs
template<typename type_t >
using	xtd::collections::generic::helpers::allocator = std::allocator< type_t >
	Represent an allocator alias.

Typedef Documentation

allocator

template<typename type_t >

using xtd::collections::generic::helpers::allocator = typedef std::allocator<type_t>

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

Represent an allocator alias.

Header

#include <xtd/collections/generic/allocator>

Namespace

xtd::collections

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 std::vector.

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