Source Link

Document

Allows iteration over the files in a given directory (and optionally its subdirectories) which match an array of extensions.

Usage

From source file:biz.paluch.maven.configurator.FileTemplating.java

/**
 * Process files which match the template pattern. Creates a new file using the input file with property
 * replacement. Target filename is without the template name part.
 *
 * @param log/* ww w.j av  a2  s  .  c  o m*/
 * @param root
 * @param processor
 * @throws IOException
 */
public static void processFiles(Log log, File root, TemplateProcessor processor) throws IOException {

    Iterator<File> iterator = FileUtils.iterateFiles(root, new RegexFileFilter(FILE_TEMPLATE_PATTERN),
            TrueFileFilter.TRUE);

    while (iterator.hasNext()) {
        File next = iterator.next();
        log.debug("Processing file " + next);
        try {
            processor.processFile(next, getTargetFile(next));
        } catch (IOException e) {
            throw new IOException("Cannot process file " + next.toString() + ": " + e.getMessage(), e);
