RapidSpellChecker (Programmatic Spell Checker)

Provides a model (business/logic) level spell checker API which can be used in a client-server environment

and any applications where a client GUI does not exist. RapidSpellChecker has been

benchmarked at checking 50,000 words/second on a standard 1GHz PC. User dictionaries can optionally

be used, allowing words to be added. This component can be used in 2 different ways, in an iterative

fashion or on a query by query basis. Please see the API docs for code level details.

Using RapidSpellChecker in an iterative manner provides complete textual correction of strings similar

to a GUI based spell checker. A string is loaded into RapidSpellChecker and then successive calls to the

nextBadWord() method move through the string allowing findSuggestions() and

changeBadWord(replacement) to be called to find spelling suggestions and optionally correct the misspelt

words in the text, finally getAmendedText() returns the corrected text.

Alternatively RapidSpellChecker may be used in a simple query by query basis, calls to lookUp(word)

and findSuggestions(word) methods allow bare bones spell checking functionality.
