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<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.
