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.
References std::swap().
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.
