nsIEditorSpellCheck Interface

 Adds a word to the current personal dictionary.

 @see nsISpellChecker::AddWordToDictionary

void AddWordToDictionary(in wstring word)

 Check a given word. In spite of the name, this function checks the word
 you give it, returning true if the word is misspelled. If the word is
 misspelled, it will compute the suggestions which you can get from
 GetSuggestedWord().

 @see nsISpellChecker::CheckCurrentWord

boolean CheckCurrentWord(in wstring suggestedWord)

 Like CheckCurrentWord, checks the word you give it, returning true if it's
 misspelled. This is faster than CheckCurrentWord because it does not
 compute any suggestions.

 Watch out: this does not clear any suggestions left over from previous
 calls to CheckCurrentWord, so there may be suggestions, but they will be
 invalid.

boolean CheckCurrentWordNoSuggest(in wstring suggestedWord)

 @see nsISpellChecker::GetCurrentDictionary

wstring GetCurrentDictionary()

 Retrieves a list of the currently available dictionaries. The strings will
 typically be language IDs, like "en-US".

 @see mozISpellCheckingEngine::GetDictionaryList

void GetDictionaryList([array, size_is(count)] out wstring dictionaryList, out PRUint32 count)

 When interactively spell checking the document, this will return the
 value of the next word that is misspelled. This also computes the
 suggestions which you can get by calling GetSuggestedWord.

 @see nsISpellChecker::GetNextMisspelledWord

wstring GetNextMisspelledWord()

 Fills an internal list of words added to the personal dictionary. These
 words can be retrieved using GetPersonalDictionaryWord()

 @see nsISpellChecker::GetPersonalDictionary
 @see GetPersonalDictionaryWord

void GetPersonalDictionary()

 Used after you call GetPersonalDictionary() to iterate through all the
 words added to the personal dictionary. Will return the empty string when
 there are no more words.

wstring GetPersonalDictionaryWord()

 Used to get suggestions for the last word that was checked and found to
 be misspelled. The first call will give you the first (best) suggestion.
 Subsequent calls will iterate through all the suggestions, allowing you
 to build a list. When there are no more suggestions, an empty string will
 be returned.

 @see nsISpellChecker::GetSuggestedWord

wstring GetSuggestedWord()

 @see nsISpellChecker::IgnoreAll

void IgnoreWordAllOccurrences(in wstring word)

 Turns on the spell checker for the given editor. enableSelectionChecking
 set means that we only want to check the current selection in the editor,
 (this controls the behavior of GetNextMisspelledWord). For inline
 spellchecking, we don't care about this.

void InitSpellChecker(in nsIEditor editor, in boolean enableSelectionChecking)

 Removes a word from the current personal dictionary.

 @see nsISpellChecker::RemoveWordFromPersonalDictionary

void RemoveWordFromDictionary(in wstring word)

 Use when modaly checking the document to replace a word.

 @see nsISpellChecker::CheckCurrentWord

void ReplaceWord(in wstring misspelledWord, in wstring replaceWord, in boolean allOccurrences)

 @see nsISpellChecker::SetCurrentDictionary

void SetCurrentDictionary(in wstring dictionary)

 Call this to free up the spell checking object. It will also save the
 current selected language as the default for future use.

 If you have called CanSpellCheck but not InitSpellChecker, you can still
 call this function to clear the cached spell check object, and no
 preference saving will happen.

void UninitSpellChecker()

 Used to filter the content (for example, to skip blockquotes in email from
 spellchecking. Call this before calling InitSpellChecker; calling it
 after initialization will have no effect.

 @see nsITextServicesDocument::setFilter

void setFilter(in nsITextServicesFilter filter)
