Detailed Description

template<typename _Tp, typename _Compare>
class __gnu_parallel::_LoserTree< false, _Tp, _Compare >

Unstable _LoserTree variant.

Stability (non-stable here) is selected with partial specialization.

Definition at line 261 of file losertree.h.

Member Function Documentation

◆ __delete_min_insert() [1/2]

void __gnu_parallel::_LoserTree< __stable, _Tp, _Compare >::__delete_min_insert ( _Tp __key,
bool __sup )
inline

Delete the smallest element and insert a new element from the previously smallest element's sequence.

This implementation is stable.

Definition at line 222 of file losertree.h.

◆ __delete_min_insert() [2/2]

template<typename _Tp, typename _Compare>
void __gnu_parallel::_LoserTree< false, _Tp, _Compare >::__delete_min_insert ( _Tp __key,
bool __sup )
inline

Delete the _M_key smallest element and insert the element __key instead.

Parameters
__keythe _M_key to insert
__suptrue iff __key is an explicitly marked supremum

Definition at line 324 of file losertree.h.

◆ __get_min_source()

int __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::__get_min_source ( )
inline
Returns
the index of the sequence with the smallest element.

◆ __init_winner() [2/2]

template<typename _Tp, typename _Compare>
unsigned int __gnu_parallel::_LoserTree< false, _Tp, _Compare >::__init_winner ( unsigned int __root)
inline

Computes the winner of the competition at position "__root".

Called recursively (starting at 0) to build the initial tree.

Parameters
__root__index of the "game" to start.

Definition at line 284 of file losertree.h.

◆ __insert_start()

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
__keythe element to insert
__source__index of the __source __sequence
__supflag that determines whether the value to insert is an explicit __supremum.
