Another category of components provides fundamental, low-level
These are low-level in the sense that you would be more likely to use them
to build other components than to use them directly in
and the ``pointer'' classes provided by
fall into this category.
For example, one of the facilities
fixed-size chunks of storage very efficiently.
It is useful in building other classes
that allocate and free many instances of some fixed-size type T.
As a proof of concept, several of the components in C++ Standard Components use Pools
for their internal storage management.
uses Pools to allocate List nodes.
