C++ – Why does the C++ STL not provide any “tree” containers

Why does the C++ STL not provide any "tree" containers, and what's the best thing to use instead?

I want to store a hierarchy of objects as a tree, rather than use a tree as a performance enhancement…

Best Solution

There are two reasons you could want to use a tree:

You want to mirror the problem using a tree-like structure:
For this we have boost graph library

Or you want a container that has tree like access characteristics For this we have

Basically the characteristics of these two containers is such that they practically have to be implemented using trees (though this is not actually a requirement).
