Detailed Description

template<bool Stable, typename ValueType, typename Comparator = std::less<ValueType>>
class tlx::LoserTreeCopy< Stable, ValueType, Comparator >

Guarded loser tree/tournament tree, either copying the whole element into the tree structure, or looking up the element via the index.

Unstable specialization of LoserTreeCopyBase.

Guarding is done explicitly through one flag sup per element, inf is not needed due to a better initialization routine. This is a well-performing variant.

Template Parameters

ValueType	the element type
Comparator	comparator to use for binary comparisons.
