Detailed Description

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.

_Tpthe element type
_Comparethe comparator to use, defaults to std::less<_Tp>

Member Function Documentation

int __gnu_parallel::_LoserTreeBase::__get_min_source ( ) [inline]
the index of the sequence with the smallest element.

Definition at line 155 of file losertree.h.

void __gnu_parallel::_LoserTreeBase::__insert_start ( const _Tp &  __key,
int  __source,
bool  __sup 
) [inline]

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

__keythe element to insert
__source__index of the __source __sequence
