Examples of TextOffset

com.ibm.richtext.textformat.TextOffset
A TextOffset indicates both an integer offset into text and a placement on one of the characters adjacent to the offset. An offset is a position between two characters; offset n is between character n-1 and character n. The placement specifies whether it is associated with the character after the offset (character n) or the character before the offset (character n-1).
Knowing which character the TextOffset is associated with is necessary when displaying carets. In bidirectional text, a single offset may have two distinct carets. Also, in multiline text, an offset at a line break has a possible caret on each line.
Most clients will not be interested in the placement, and will just use the offset.

    // sigh... look out for aliasing
    public void setSelectionRange(TextOffset newStart, TextOffset newLimit, TextOffset newAnchor) {


        boolean zeroLengthChange = rangeIsZeroLength(newStart, newLimit, newAnchor) != 
                                    rangeIsZeroLength(fStart, fLimit, fAnchor);
        TextOffset tempNewAnchor;
        if (newAnchor == fStart || newAnchor == fLimit) {
            tempNewAnchor = new TextOffset(newAnchor); // clone in case of aliasing
        }
        else {
            tempNewAnchor = newAnchor;
