Detailed Description¶
template<typename _Tp, typename _Compare>¶
class __gnu_parallel::_LoserTreeBase< _Tp, _Compare >" Guarded loser/tournament tree.
The smallest element is at the top.
Guarding is done explicitly through one flag _M_sup per element, inf is not needed due to a better initialization routine. This is a well-performing variant.
Parameters:
_Compare the comparator to use, defaults to std::less<_Tp>

template<typename _Tp , typename _Compare > void __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::__insert_start (const _Tp & __key, int __source, bool __sup) [inline]¶

Parameters:
__source __index of the __source __sequence
