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.
