xtd::ranges::views::distinct_view Class Reference

Definition

The xtd::ranges::views::distinct_view class is used to distinct elements from a sequence.

Definition

class distinct_view;

Header

#include <xtd/ranges/views/distinct_view>

Namespace

xtd::ranges::views

Library

xtd.core

Examples

The following example shows how to use xtd::ranges::views::distinct instance :

#include <xtd/xtd>
 
auto main() -> int {
  auto numbers = array {2, 7, 3, 1, 1, 4, 10, 5, 3, 3, 3, 6, 6, 2, 8, 9, 8, 9};
  console::write_line("numbers = {}", numbers | distinct);
}
 
// This code produces the following output :
//
// numbers = [2, 7, 3, 1, 4, 10, 5, 6, 8, 9]

The following example shows how to use xtd::ranges::views::distinct_view class :

#include <xtd/xtd>
 
auto main() -> int {
  auto numbers = array {2, 7, 3, 1, 1, 4, 10, 5, 3, 3, 3, 6, 6, 2, 8, 9, 8, 9};
  console::write_line("numbers = {}", distinct(numbers));
}
 
// This code produces the following output :
//
// numbers = [2, 7, 3, 1, 4, 10, 5, 6, 8, 9]

Public Operators
template<std::ranges::range range_t>
auto	operator() (range_t &&source) const
	Returns distinct elements from a sequence by using the default equality comparer to compare values.
template<std::ranges::range range_t, typename comparer_t>
auto	operator() (range_t &&source, const comparer_t &comparer) const
	Returns distinct elements from a sequence by using a specified xtd::collections::generic::iequality_comparer <type_t> to compare values.
template<typename comparer_t>
auto	operator() (const comparer_t &comparer) const
	Returns distinct elements from a sequence by using a specified xtd::collections::generic::iequality_comparer <type_t> to compare values.
