Detailed Description
template<bool stable, typename T, typename Comparator> class
__gnu_parallel::LoserTree< stable, T, Comparator >
Stable LoserTree variant.
Provides the stable implementations of insert_start, init_winner, init
and delete_min_insert.
Unstable variant is done using partial specialisation below.

Member Function Documentation
template<bool stable, typename T , typename Comparator > void
__gnu_parallel::LoserTree< stable, T, Comparator >::delete_min_insert
(T 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 215 of file losertree.h.
template<typename T , typename Comparator > int
__gnu_parallel::LoserTreeBase< T, Comparator >::get_min_source ()
[inline, inherited] Returns:
the index of the sequence with the smallest element.

template<typename T , typename Comparator > void
__gnu_parallel::LoserTreeBase< T, Comparator >::insert_start (const T &
key, int source, bool sup) [inline, inherited]
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.
