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 260 of file losertree.h.

Member Function Documentation

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

__key	the _M_key to insert
__sup	true iff __key is an explicitly marked supremum

Definition at line 322 of file losertree.h.

template<typename _Tp , typename _Compare >

int __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::__get_min_source ( )

inlineinherited

Returns

the index of the sequence with the smallest element.

Definition at line 155 of file losertree.h.

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 282 of file losertree.h.

template<typename _Tp , typename _Compare >

void __gnu_parallel::_LoserTreeBase< _Tp, _Compare >::__insert_start ( const _Tp &  __key, int  __source, bool  __sup  )

inlineinherited

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

Parameters

__key	the element to insert
__source	__index of the __source __sequence
__sup	flag that determines whether the value to insert is an explicit __supremum.
