Provides the stable implementations of insert_start, init_winner, init and delete_min_insert.
Unstable variant is done using partial specialisation below.

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.

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".
key | the element to insert | |
source | index of the source sequence | |
sup | flag that determines whether the value to insert is an explicit supremum. |
