Document

Return a Stream that is lazily populated with Path by searching for files in a file tree rooted at a given starting file.

Usage

From source file:gedi.util.FileUtils.java

public static String[] find(String path, String glob, boolean stripPath) throws IOException {
    if (!path.endsWith("/"))
        path = path + "/";
    String cpath = path;/*  w w  w. jav a 2  s  .c om*/
    ArrayList<String> re = new ArrayList<String>();
    PathMatcher matcher = FileSystems.getDefault().getPathMatcher("glob:" + path + glob);
    Files.find(Paths.get(path), 9999, (p, per) -> {
        return matcher.matches(p);
    }, FileVisitOption.FOLLOW_LINKS).forEach(f -> {
        String file = f.toString();
        if (stripPath && file.startsWith(cpath))
            file = file.substring(cpath.length());
        re.add(file);
    });
    return re.toArray(new String[0]);
