Enhancement: Style Match

Hi Tomas, I am trying to implement a search for similar text.
I can find similar strings, but I am trying to find a way to match the style. I am doing ths:

public static ArrayList<IndexRange> getIndexRangesOfStyledDocInTextArea(StyledDocument styledDocToFind, InlineCssTextArea richTextArea) {
    ArrayList<IndexRange> ranges = new ArrayList<>();

    String textBody = richTextArea.getText();

    int start = 0;
    while (true) {
        int found = textBody.indexOf(styledDocToFind.getText(), start);
        if (found != -1) {
            // Found a similar string, now lets match the style -- do whatever here

            IndexRange range = new IndexRange(found, found + styledDocToFind.length());

            StyledDocument foundDoc = richTextArea.getDocument().subSequence(range);
            StyleSpans foundSpans = foundDoc.getStyleSpans(0);
            StyleSpans givenSpans = styledDocToFind.getStyleSpans(0);

            int foundSpanCount = foundSpans.getSpanCount();
            int givenSpanCount = givenSpans.getSpanCount();

            boolean match = true;//assume we found it
            for (int i = 0; i < foundSpanCount; i++) {
                if (foundSpans.getStyleSpan(i).getStyle() != givenSpans.getStyleSpan(i).getStyle()) {
                    match = false;
                    break;
                }
            }

            //if assumptions hold true then..
            if (match) {
                ranges.add(range);
            }

        }
        if (found == -1) {
            break;
        }
        start = found + 2;  // move start up for next iteration
    }

    return ranges;
}

But I can't seem to get it. How do you suggest I find an exact match (string+ style)?

Hi Maher,

the problems I see with your code:

1. you are not checking whether foundSpanCount == givenSpanCount
2. you are not comparing the lengths of individual spans (whether foundSpans.getStyleSpan(i).getLength() == givenSpans.getStyleSpan(i).getLength())
3. you should use equals instead of == to compare style objects, i.e. !foundSpans.getStyleSpan(i).getStyle().equals(givenSpans.getStyleSpan(i).getStyle()) instead of foundSpans.getStyleSpan(i).getStyle() != givenSpans.getStyleSpan(i).getStyle()

I just implemented equals on StyleSpans, so now you can use

boolean match = foundSpans.equals(givenSpans);

I knew you were going to do it :)
Thanks!
