Classes¶

struct _Loser
Internal representation of a _LoserTree element.

Public Member Functions¶

_LoserTreeBase (unsigned int __k, _Compare __comp)
The constructor. ~_LoserTreeBase ()
The destructor. int __get_min_source ()
void __insert_start (const _Tp &__key, int __source, bool __sup)
Initializes the sequence '_M_source' with the element '__key'.

Protected Attributes¶

_Compare _M_comp
_Compare to use. bool _M_first_insert
State flag that determines whether the _LoserTree is empty. unsigned int _M_ik
unsigned int _M_k
unsigned int _M_log_k
_Loser * _M_losers
_LoserTree __elements. unsigned int _M_offset

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

template<typename _Tp , typename _Compare > __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::_LoserTreeBase (unsigned int __k, _Compare __comp) [inline]¶

The constructor.

Parameters

References __gnu_parallel::__rd_log2(), __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::_M_first_insert, __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::_M_log_k, and __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::_M_losers.

template<typename _Tp , typename _Compare > __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::~_LoserTreeBase () [inline]¶

The destructor.

template<typename _Tp , typename _Compare > int __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::__get_min_source () [inline]¶

Returns

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

Initializes the sequence '_M_source' with the element '__key'.

Parameters

References __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::_M_first_insert, __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::_Loser::_M_key, __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::_M_losers, __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::_Loser::_M_source, and __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::_Loser::_M_sup.

template<typename _Tp , typename _Compare > _Compare __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::_M_comp [protected]¶

_Compare to use.

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