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 > 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'.

template<typename _Tp , typename _Compare > bool __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::_M_first_insert [protected], [inherited]¶

State flag that determines whether the _LoserTree is empty. Only used for building the _LoserTree.
