NAME¶
__gnu_parallel::_LoserTreeBase< _Tp, _Compare > - Guarded loser/tournament tree.
SYNOPSIS¶
#include <losertree.h>
Inherited by __gnu_parallel::_LoserTree< __stable, _Tp, _Compare >, and __gnu_parallel::_LoserTree< false, _Tp, _Compare >.
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
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>
