<P>
Interface for associating a SAX event with a document location.
<blockquote>
<em>This module, both source code and documentation, is in the
Public Domain, and comes with <strong>NO WARRANTY</strong>.</em>
</blockquote>
<p>If a SAX parser provides location information to the SAX
application, it does so by implementing this interface and then
passing an instance to the application using the content
handler's <A HREF="../../../org/xml/sax/ContentHandler.html#setDocumentLocator(org.xml.sax.Locator)"><CODE>setDocumentLocator</CODE></A> method. The application can use the
object to obtain the location of any other content handler event
in the XML source document.</p>
<p>Note that the results returned by the object will be valid only
during the scope of each content handler method: the application
will receive unpredictable results if it attempts to use the
locator at any other time.</p>
<p>SAX parsers are not required to supply a locator, but they are
very strongly encouraged to do so. If the parser supplies a
locator, it must do so before reporting any other document events.
If no locator has been set by the time the application receives
the <A HREF="../../../org/xml/sax/ContentHandler.html#startDocument()"><CODE>startDocument</CODE></A>
event, the application should assume that a locator is not
available.</p>
