Detailed Description

template<bool __stable, typename _Tp, typename _Compare>
class __gnu_parallel::_LoserTree< __stable, _Tp, _Compare >

Stable _LoserTree variant.

Provides the stable implementations of insert_start, __init_winner, __init and __delete_min_insert.

Unstable variant is done using partial specialisation below.

template<bool __stable, typename _Tp , typename _Compare >

void __gnu_parallel::_LoserTree< __stable, _Tp, _Compare >::__delete_min_insert	(	_Tp	__key,
		bool	__sup
	)		[inline]

Delete the smallest element and insert a new element from the previously smallest element's sequence.

This implementation is stable.

template<typename _Tp , typename _Compare >

int __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::__get_min_source

(

)

[inline, inherited]

Returns:

the index of the sequence with the smallest element.

template<typename _Tp , typename _Compare >

void __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::__insert_start	(	const _Tp &	__key,
		int	__source,
		bool	__sup
	)		[inline, inherited]

Initializes the sequence "_M_source" with the element "__key".

Parameters:

__key	the element to insert
__source	__index of the __source __sequence
__sup	flag that determines whether the value to insert is an explicit __supremum.
