virtual

const virtual void destroy()

Destroys this Stemmer.

This function is called by Zorba when the Stemmer is no longer needed.

If your StemmerProvider dynamically allocates Stemmer objects, then the implementation can simply be (and usually is) delete this.

If your StemmerProvider returns a pointer to a static Stemmer object, then the implementation should do nothing.

const virtual void stem(
    String const & word,
    locale::iso639_1::type lang,
    String * result
)

Stems the given word.

word	The word to stem.
lang	The language of the word.
result	The stemmed word (or the original word if either it and its stem are the same word or the stemmer doesn't know how to stem it).
