Returns an Iterator over the entire set of members, including copies due to cardinality.

Usage

From source file:org.apache.maven.shared.jar.identification.exposers.TimestampExposer.java

public void expose(JarIdentification identification, JarAnalyzer jarAnalyzer) {
    List entries = jarAnalyzer.getEntries();
    SimpleDateFormat tsformat = new SimpleDateFormat("yyyyMMdd", Locale.US); //$NON-NLS-1$
    Bag timestamps = new HashBag();
    Iterator it = entries.iterator();
    while (it.hasNext()) {
        JarEntry entry = (JarEntry) it.next();
        long time = entry.getTime();
        String timestamp = tsformat.format(new Date(time));
        timestamps.add(timestamp);/*w  ww  . java 2s . co m*/
    }

    it = timestamps.iterator();
    String ts = "";
    int tsmax = 0;
    while (it.hasNext()) {
        String timestamp = (String) it.next();
        int count = timestamps.getCount(timestamp);
        if (count > tsmax) {
            ts = timestamp;
            tsmax = count;
        }
    }

    if (StringUtils.isNotEmpty(ts)) {
        identification.addVersion(ts);
