get an iterator of the Entry instances contained directly in this instance (in other words, children only; no grandchildren etc.)

Usage

From source file:FeatureExtraction.FeatureExtractorDocStreamPaths.java

private static void GetStreamsPaths(DirectoryNode dir, String parentPath, Map<String, Integer> streamPaths) {
    // run over all directory chidlrens
    for (Iterator<Entry> entryIter = dir.getEntries(); entryIter.hasNext();) {
        Entry entry = entryIter.next();//from w w  w .  j  a  va2  s .c o m
        String entryName = entry.getName();

        // Some entry names starts with binary value that are not printable - remove it
        if (entryName.charAt(0) < 10) {
            entryName = entryName.substring(1);
        }

        // Recursively search for directory (storage) children
        if (entry instanceof DirectoryNode) {
            GetStreamsPaths((DirectoryNode) entry, parentPath + "\\" + entryName, streamPaths);
        } else {
            // Add stream path to set of paths
            String filePath = parentPath + "\\" + entryName;
            AddStreamPath(filePath, streamPaths);
        }
    }
