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.

__delete_min_insert()

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.

__get_min_source()

template<typename _Tp , typename _Compare >

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

inlineinherited

Returns

the index of the sequence with the smallest element.

__insert_start()

template<typename _Tp , typename _Compare >

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

inlineinherited

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.
