If you wish this to be automatically done, then you can subclass from this class

and implement your own special

insert()

and

remove()

functions which

perform a

resize()

as necessary.

Example

Program output:

The table does contain Oregon

The table does not contain Oregon

#include <rw/tvhasht.h>

#include <rw/cstring.h>

#include <rw/rstream.h>

unsigned hashIt(const RWCString& str) {return str.hash();}

main()

{

RWTValHashTable<RWCString> table(hashIt);

table.insert("Alabama"); // NB: Type conversion occurs

table.insert("Pennsylvania");

table.insert("Oregon");

table.insert("Montana");

cout << "The table " <<

(table.contains("Oregon") ? "does " : "does not ") <<

"contain Oregon\n";

table.removeAll("Oregon");

cout << "The table " <<

(table.contains("Oregon") ? "does " : "does not ") <<

"contain Oregon";

return 0;
