xtd::collections::generic::helpers Namespace Reference

Definition

The xtd::collections::generic::helpers namespace contains helpers for generic collections, sush as comparer, equator an hasher structs.

The xtd::collections::generic::helpers namespace contains helpers for generic collections, sush as lesser, equator an hasher structs.

Classes
struct	comparer
	Implements a function object for compare data. More...
struct	equator
	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 xtd::any_object. More...
struct	hasher
	Implements a function object for hashing data. More...
struct	lesser
	Implements a function object for compare data. More...
class	wrap_pointer_iterator
	Represents a wrap pointer iterator. More...

Alias
template<class value_t , class iterator_tag_t = std::random_access_iterator_tag>
using	wrap_pointer_reverse_iterator = std::reverse_iterator< wrap_pointer_iterator< value_t, iterator_tag_t > >
	Represents a wrap pointer reverse iterator.

Aliases
template<class type_t >
using	allocator = std::allocator< type_t >
	Represent an allocator alias.
template<class input_iterator_t >
using	iterator_value_t = typename std::iterator_traits< input_iterator_t >::value_type
	Represents the value iterator type.
template<class input_iterator_t >
using	iterator_key_t = std::remove_const_t< std::tuple_element_t< 0, iterator_value_t< input_iterator_t > > >
	Represents the key iterator type.
template<class input_iterator_t >
using	iterator_mapped_t = std::tuple_element_t< 1, iterator_value_t< input_iterator_t > >
	Represents the mapped iterator type.
template<class input_iterator_t >
using	iterator_to_allocator_t = std::pair< std::add_const_t< iterator_key_t< input_iterator_t > >, iterator_mapped_t< input_iterator_t > >
	Represents the iterator to allocator type.
