21    * <p>This class is available mainly for application writers, who
22    * can use it to make a persistent snapshot of a locator at any
23    * point during a document parse:</p>
24    *
25    * <pre>
26    * Locator locator;
27    * Locator startloc;
28    *
29    * public void setLocator (Locator locator)
30    * {
31    * // note the locator
32    * this.locator = locator;
33    * }
34    *
35    * public void startDocument ()
36    * {
37    * // save the location of the start of the document
38    * // for future use.
39    * Locator startloc = new LocatorImpl(locator);
40    * }
41    *</pre>
42    *
43    * <p>Normally, parser writers will not use this class, since it
44    * is more efficient to provide location information only when
45    * requested, rather than constantly updating a Locator object.</p>
