WebUnordered associative containers are Container s that provide fast lookup of objects based on keys. Worst case complexity is linear but on average much faster for most of … Webset, multiset , map and multimap associative containers are implemented as binary search trees which offer the needed complexity and stability guarantees required by the C++ standard for associative containers. Boost.Container offers the possibility to configure at compile time some parameters of the binary search tree implementation.
