THE ADVANCED C++ SIG OF SOFTWARE FORUM 
on Friday, August 11, 6:15 p.m.
presents 

 Extending the STL Library:  A Case Study For Hash Tables

		  Dr. Robert Fraley
                Hewlett-Packard

			 Abstract

The STL library provides container classes and algorithms,
and has been accepted as part of the draft C++ standard. 
While this library is sizable, it may be extended to include
other data structures and algorithms.

Currently, the STL has the following associative containers:
sets, multisets, maps, and multimaps.  These associative
containers store entries in sorted order.  A properly
constructed hash table will not need to be sorted
and thus will allow for faster insertion and lookups. 
Dr. Fraley wrote one of the hash tables placed in the public
domain which is available via anonymous ftp at
butler.hpl.hp.com under stl/hashbf.

We shall discuss the definition of hash table properties and
the various members required to be defined to match the STL
requirements.  Code will be shown.  The implementation uses
STL containers.
