rw_hashset<T,Hash,EQ> set;
Description
Class rw_hashset<T,Hash,EQ> maintains a collection of T, implemented as a hash table in
which there may not be more than one instance of any given T. Since this is a value based
collection, objects are copied into and out of the collection. As with all classes that meet the
ANSI associative container specification, rw_hashset provides for iterators that reference its
elements. Operations that alter the contents of rw_hashset may invalidate other iterators that
reference the container. Since the contents of rw_hashset are in pseudo-random order, the only
iterator ranges that will usually make sense are the results of calling equal_range(key), and the
entire range from begin() to end().
