Detailed Description

template<typename T, typename Comparator>
class __gnu_parallel::LoserTree< false, T, Comparator >

Unstable LoserTree variant.

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

Definition at line 251 of file losertree.h.

Member Function Documentation

template<typename T , typename Comparator >

void __gnu_parallel::LoserTree< false, T, Comparator >::delete_min_insert ( T  key, bool  sup  )

inline

Delete the key smallest element and insert the element key instead.

Parameters

key	the key to insert
sup	true iff key is an explicitly marked supremum

Definition at line 312 of file losertree.h.

template<typename T , typename Comparator >

int __gnu_parallel::LoserTreeBase< T, Comparator >::get_min_source ( )

inlineinherited

Returns

the index of the sequence with the smallest element.

template<typename T , typename Comparator >

unsigned int __gnu_parallel::LoserTree< false, T, Comparator >::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 273 of file losertree.h.

References std::left(), and std::right().

template<typename T , typename Comparator >

void __gnu_parallel::LoserTreeBase< T, Comparator >::insert_start ( const T &  key, int  source, bool  sup  )

inlineinherited

Initializes the sequence "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.
