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.

Member Function Documentation

template<bool __stable, typename _Tp , typename _Compare >
void __gnu_parallel::_LoserTree< __stable, _Tp, _Compare >::__delete_min_insert ( _Tp  __key,
bool  __sup 

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 ( )
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 

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

__keythe element to insert
__source__index of the __source __sequence
__supflag that determines whether the value to insert is an explicit __supremum.
