## Detailed Description

### template<typename _Tv, typename Cmp_Fn = std::less<_Tv>, typename Tag = pairing_heap_tag, typename _Alloc = std::allocator<char>>
class __gnu_pbds::priority_queue< _Tv, Cmp_Fn, Tag, _Alloc >

A priority queue composed of one specific heap policy.

Template Parameters

  _Tv | Value type.
  Cmp_Fn | Comparison functor.
  Tag | Instantiating data structure type, see container_tag.
  _Alloc | Allocator type.

Base is dispatched at compile time via Tag, from the following choices: binary_heap_tag, binomial_heap_tag, pairing_heap_tag, rc_binomial_heap_tag, thin_heap_tag

Base choices are: detail::binary_heap, detail::binomial_heap, detail::pairing_heap, detail::rc_binomial_heap, detail::thin_heap.

## Constructor & Destructor Documentation

## priority_queue() [1/3]

template<typename _Tv , typename Cmp_Fn = std::less<_Tv>, typename Tag = pairing_heap_tag, typename _Alloc = std::allocator<char>>

__gnu_pbds::priority_queue< _Tv, Cmp_Fn, Tag, _Alloc >::priority_queue | ( | const cmp_fn & | r_cmp_fn | ) |

inline

Constructor taking some policy objects. r_cmp_fn will be copied by the Cmp_Fn object of the container object.

Definition at line 116 of file priority_queue.hpp.

## priority_queue() [2/3]

template<typename _Tv , typename Cmp_Fn = std::less<_Tv>, typename Tag = pairing_heap_tag, typename _Alloc = std::allocator<char>>
template<typename It >

__gnu_pbds::priority_queue< _Tv, Cmp_Fn, Tag, _Alloc >::priority_queue | ( | It | first_it,
|  | It | last_it
| ) |  |

inline

Constructor taking __iterators to a range of value_types. The value_types between first_it and last_it will be inserted into the container object.

Definition at line 122 of file priority_queue.hpp.

## priority_queue() [3/3]

template<typename _Tv , typename Cmp_Fn = std::less<_Tv>, typename Tag = pairing_heap_tag, typename _Alloc = std::allocator<char>>
template<typename It >

__gnu_pbds::priority_queue< _Tv, Cmp_Fn, Tag, _Alloc >::priority_queue | ( | It | first_it,
|  | It | last_it,
|  | const cmp_fn & | r_cmp_fn
| ) |  |

inline

Constructor taking __iterators to a range of value_types and some policy objects The value_types between first_it and last_it will be inserted into the container object. r_cmp_fn will be copied by the cmp_fn object of the container object.
