# \_\_gnu\_parallel::LoserTreePointerUnguardedBase(3)

## NAME

\_\_gnu\_parallel::LoserTreePointerUnguardedBase -

## SYNOPSIS

Inherited by **\_\_gnu\_parallel::LoserTreePointerUnguarded\< stable, T, Comparator \>**, and **\_\_gnu\_parallel::LoserTreePointerUnguarded\< false, T, Comparator \>**.

## Detailed Description

### template\<typename T, typename Comparator\> class \_\_gnu\_parallel::LoserTreePointerUnguardedBase\< T, Comparator \>

Unguarded loser tree, keeping only pointers to the elements in the tree structure.

No guarding is done, therefore not a single input sequence must run empty. This is a very fast variant.
