Detailed Description

Abstractions for uniform iterating through various underlying types.

Function Documentation

◆ __iterator_category()

template<typename _Iter >
constexpr iterator_traits<_Iter>::iterator_category std::__iterator_category ( const _Iter &  )
inlineconstexpr

◆ back_inserter()

template<typename _Container >
constexpr back_insert_iterator<_Container> std::back_inserter ( _Container &  __x)
inlineconstexpr
Parameters
__xA container of arbitrary type.
Returns
An instance of back_insert_iterator working on __x.

This wrapper function helps in creating back_insert_iterator instances. Typing the name of the iterator requires knowing the precise full type of the container, which can be tedious and impedes generic programming. Using this function lets you take advantage of automatic template parameter deduction, making the compiler match the correct types for you.

Definition at line 718 of file bits/stl_iterator.h.

◆ front_inserter()

template<typename _Container >
constexpr front_insert_iterator<_Container> std::front_inserter ( _Container &  __x)
inlineconstexpr
Parameters
__xA container of arbitrary type.
Returns
An instance of front_insert_iterator working on x.

This wrapper function helps in creating front_insert_iterator instances. Typing the name of the iterator requires knowing the precise full type of the container, which can be tedious and impedes generic programming. Using this function lets you take advantage of automatic template parameter deduction, making the compiler match the correct types for you.

◆ inserter()

template<typename _Container >
insert_iterator<_Container> std::inserter ( _Container &  __x,
typename _Container::iterator  __i 
)
inline
Parameters
__xA container of arbitrary type.
__iAn iterator into the container.
Returns
An instance of insert_iterator working on __x.

This wrapper function helps in creating insert_iterator instances. Typing the name of the iterator requires knowing the precise full type of the container, which can be tedious and impedes generic programming. Using this function lets you take advantage of automatic template parameter deduction, making the compiler match the correct types for you.

◆ make_reverse_iterator()

template<typename _Iterator >
constexpr reverse_iterator<_Iterator> std::make_reverse_iterator ( _Iterator  __i)
inlineconstexpr

Generator function for reverse_iterator.

Definition at line 587 of file bits/stl_iterator.h.

◆ operator==()

template<typename _Iterator >
constexpr bool std::operator== ( const reverse_iterator< _Iterator > &  __x,
const reverse_iterator< _Iterator > &  __y 
)
inlineconstexpr
Parameters
__xA reverse_iterator.
__yA reverse_iterator.
Returns
A simple bool.

Reverse iterators forward comparisons to their underlying base() iterators.
