• Constructor Detail

  • WordIterator

    public WordIterator()

    Constructs a WordIterator using the default locale.

  • WordIterator

    public WordIterator(Locale locale)

    Constructs a new WordIterator for the specified locale.

    Parameters:

    locale - The locale to be used when analysing the text.

• Method Detail

  • setCharSequence

    public void setCharSequence(CharSequence charSequence,
                       int start,
                       int end)

  • preceding

    public int preceding(int offset)

    Specified by:

    preceding in interface Selection.PositionIterator

  • following

    public int following(int offset)

    Specified by:

    following in interface Selection.PositionIterator

  • getBeginning

    public int getBeginning(int offset)

    If offset is within a word, returns the index of the first character of that word, otherwise returns BreakIterator.DONE. The offsets that are considered to be part of a word are the indexes of its characters, as well as the index of its last character plus one. If offset is the index of a low surrogate character, BreakIterator.DONE will be returned. Valid range for offset is [0..textLength] (note the inclusive upper bound). The returned value is within [0..offset] or BreakIterator.DONE.

    Throws:

    IllegalArgumentException - is offset is not valid.

  • getEnd

    public int getEnd(int offset)

    If offset is within a word, returns the index of the last character of that word plus one, otherwise returns BreakIterator.DONE. The offsets that are considered to be part of a word are the indexes of its characters, as well as the index of its last character plus one. If offset is the index of a low surrogate character, BreakIterator.DONE will be returned. Valid range for offset is [0..textLength] (note the inclusive upper bound). The returned value is within [offset..textLength] or BreakIterator.DONE.

    Throws:

    IllegalArgumentException - is offset is not valid.
