tlx

TLX is a collection of sophisticated C++ data structures, algorithms, and miscellaneous helpers. It contains: - The fast tournament (loser) trees from MCSTL by Johannes Singler, with many fixes. - A fast intrusive reference counter called CountingPtr, which has considerably less overhead than std::shared_ptr. - Efficient and fast multiway merging algorithms from Johannes Singler, which were previously included with gcc. The tlx version has many fixes and is available for clang and MSVC++. - Many string manipulation algorithms for std::string. - An improved version of the stx-btree implementation, which is basically always a better alternative to std::map (but not std::unordered_map). - A copy of siphash for string hashing. - Efficient sequential string sorting implementations such as radix sort and multikey quicksort. - Much more; see the doxygen documentation.
