Public Member Functions¶

priority_queue (const cmp_fn &r_cmp_fn)
Constructor taking some policy objects. r_cmp_fn will be copied by the Cmp_Fn object of the container object. priority_queue (const priority_queue &other)
template<typename It > priority_queue (It first_it, It last_it)
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. template<typename It > priority_queue (It first_it, It last_it, const cmp_fn &r_cmp_fn)
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. priority_queue & operator= (const priority_queue &other)
void swap (priority_queue &other)

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

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.

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.

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.

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.
