public class LocatorImpl extends Object implements 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.
Since: SAX 1.0
Version: 2.0.1 (sax2r2)

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.
