public class LocatorImpl extends Object implements Locator
This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY.
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.
Since: SAX 1.0
Version: 2.0r2pre

This will not normally be useful, since the main purpose of this class is to make a snapshot of an existing Locator.
Create a persistent copy of the current state of a locator. When the original locator changes, this copy will still keep the original values (and it can be used outside the scope of DocumentHandler methods).
Parameters: locator The locator to copy.
Returns: The column number as an integer, or -1 if none is available.
