<hr><a name="_details"></a><h2>Detailed Description</h2>
Receive notification of general document events.
<p>
This is the main interface that most SAX applications implement: if the application needs to be informed of basic parsing events, it implements this interface and registers an instance with the SAX parser using the setDocumentHandler method. The parser uses the instance to report basic document-related events like the start and end of elements and character data.<p>
The order of events in this interface is very important, and mirrors the order of information in the document itself. For example, all of an element's content (character data, processing instructions, and/or subelements) will appear, in order, between the startElement event and the corresponding endElement event.<p>
Application writers who do not want to implement the entire interface while can derive a class from <a class="el" href="classHandlerBase.html" title="Default base class for handlers.">HandlerBase</a>, which implements the default functionality; parser writers can instantiate <a class="el" href="classHandlerBase.html" title="Default base class for handlers.">HandlerBase</a> to obtain a default handler. The application can find the location of any document event using the <a class="el" href="classLocator.html" title="Interface for associating a SAX event with a document location.">Locator</a> interface supplied by the <a class="el" href="classParser.html" title="Basic interface for SAX (Simple API for XML) parsers.">Parser</a> through the setDocumentLocator method.<p>

<p>
Receive an object for locating the origin of SAX document events.
<p>
SAX parsers are strongly encouraged (though not absolutely required) to supply a locator: if it does so, it must supply the locator to the application by invoking this method before invoking any of the other methods in the <a class="el" href="classDocumentHandler.html" title="Receive notification of general document events.">DocumentHandler</a> interface.<p>
The locator allows the application to determine the end position of any document-related event, even if the parser is not reporting an error. Typically, the application will use this information for reporting its own errors (such as character content that does not match an application's business rules). The information returned by the locator is probably not sufficient for use with a search engine.<p>
Note that the locator will return correct information only during the invocation of the events in this interface. The application should not attempt to use it at any other time.<p>
