# LetterTokenizer Class

A LetterTokenizer is a tokenizer that divides text at non-letters. That's to say, it defines tokens as maximal strings of adjacent letters, as defined by java.lang.Character.isLetter() predicate. Note: this does a decent job for most European languages, but does a terrible job for some Asian languages, where words are not separated by spaces.

For a list of all members of this type, see LetterTokenizer Members.
