Detailed Description

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

void __gnu_parallel::_LoserTree::__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.

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

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

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.
