LocatorImpl

public class LocatorImpl extends Object
implements Locator
Known Direct Subclasses

Provide an optional convenience implementation of Locator.

This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY. See http://www.saxproject.org for further information.

This class is available mainly for application writers, who can use it to make a persistent snapshot of a locator at any point during a document parse:

 Locator locator;
 Locator startloc;

 public void setLocator (Locator locator)
 {
         // note the locator
   this.locator = locator;
 }

 public void startDocument ()
 {
         // save the location of the start of the document
         // for future use.
   Locator startloc = new LocatorImpl(locator);
 }

Normally, parser writers will not use this class, since it is more efficient to provide location information only when requested, rather than constantly updating a Locator object.
