StringSet

The StringSet object is container that stores one or more unique strings. It is similar to an array or vector (e.g. Vector) but has the advantage of using a dictionary system to locate strings rather than numeric indexes. You can therefore lookup strings much more quickly than by linearly searching a Vector.

You can create a new StringSet using the DOpusFactory object. A StringSet can be either case-sensitive ("cat" and "CAT" would be treated as two different strings) or case-insensitive.
