Decorates the specified iterator such that it cannot be modified.

Usage

From source file:org.apache.hadoop.hbase.CompoundConfiguration.java

@Override
public Iterator<Map.Entry<String, String>> iterator() {
    Map<String, String> ret = new HashMap<String, String>();

    // add in reverse order so that oldest get overridden.
    if (!configs.isEmpty()) {
        for (int i = configs.size() - 1; i >= 0; i--) {
            ImmutableConfigMap map = configs.get(i);
            Iterator<Map.Entry<String, String>> iter = map.iterator();
            while (iter.hasNext()) {
                Map.Entry<String, String> entry = iter.next();
                ret.put(entry.getKey(), entry.getValue());
            }/*  www. j  av  a  2s .  co  m*/
        }
    }

    // add mutations to this CompoundConfiguration last.
    if (mutableConf != null) {
        Iterator<Map.Entry<String, String>> miter = mutableConf.iterator();
        while (miter.hasNext()) {
            Map.Entry<String, String> entry = miter.next();
            ret.put(entry.getKey(), entry.getValue());
        }
