Detailed Description

template<typename ValueType, typename Comparator = std::less<ValueType>>
class tlx::LoserTreeCopyUnguardedBase< ValueType, Comparator >

Unguarded loser tree, copying the whole element into the tree structure.

This is a base class for the LoserTreeCopyUnguarded<true> and <false> classes.

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