All Implemented Interfaces:

Locator, XMLReader

Direct Known Subclasses:

TreeDriver
```
public class DOMDriver
extends Object
implements Locator, XMLReader
```
DOMDriver.java: (pseudo-)SAX driver for DOM.
This class simulates the action of a SAX Parser, taking an already-constructed DOM Document and walking around it in a depth-first traversal, calling a SAX-compliant ContentHandler to process the children as it does so.

```
public void setContentHandler(ContentHandler handler)
```
    Set the content handler.
    
    Specified by:
    
    setContentHandler in interface XMLReader
    
    Parameters:
    
    handler - The object to receive content events. If this also implements LexicalHandler, it will also be notified of comments.
  - getContentHandler
```
public ContentHandler getContentHandler()
```
    Specified by:
    
    getContentHandler in interface XMLReader
  - setLocale
```
public void setLocale(Locale locale)
               throws SAXException
```
    SAX1: Sets the locale used for diagnostics; currently, only locales using the English language are supported.
    
    Parameters:
    
    locale - The locale for which diagnostics will be generated
    
    Throws:
    
    SAXException
  - getEntityResolver
```
public EntityResolver getEntityResolver()
```
    SAX2: Returns the object used when resolving external entities during parsing (both general and parameter entities).
    
    Specified by:
    
    getEntityResolver in interface XMLReader
  - setEntityResolver
```
public void setEntityResolver(EntityResolver resolver)
```
    SAX1, SAX2: Set the entity resolver for this parser.
    
    Specified by:
    
    setEntityResolver in interface XMLReader
    
    Parameters:
    
    resolver - The object to receive entity events.
  - getDTDHandler
```
public DTDHandler getDTDHandler()
```
    SAX2: Returns the object used to process declarations related to notations and unparsed entities.
    
    Specified by:
    
    getDTDHandler in interface XMLReader
  - setDTDHandler
```
public void setDTDHandler(DTDHandler handler)
```
    SAX1, SAX2: Set the DTD handler for this parser.
    
    Specified by:
    
    setDTDHandler in interface XMLReader
    
    Parameters:
    
    handler - The object to receive DTD events.
  - setDocumentHandler
```
public void setDocumentHandler(DocumentHandler handler)
```
    Deprecated.
    SAX2 programs should use the XMLReader interface and a ContentHandler.
    
    SAX1: Set the document handler for this parser. If a content handler was set, this document handler will supplant it. The parser is set to report all XML 1.0 names rather than to filter out "xmlns" attributes (the "namespace-prefixes" feature is set to true).
    
    Parameters:
    
    handler - The object to receive document events.
  - setErrorHandler
```
public void setErrorHandler(ErrorHandler handler)
```
    SAX1, SAX2: Set the error handler for this parser.
    
    Specified by:
    
    setErrorHandler in interface XMLReader
    
    Parameters:
    
    handler - The object to receive error events.
  - getErrorHandler
```
public ErrorHandler getErrorHandler()
```
    SAX2: Returns the object used to receive callbacks for XML errors of all levels (fatal, nonfatal, warning); this is never null;
    
    Specified by:
    
    getErrorHandler in interface XMLReader
  - setStartNode
```
public void setStartNode(Node start)
```
    Set the DOM Document that will be walked
  - parse
```
public void parse(InputSource source)
           throws SAXException
```
    Parse from InputSource. The InputSource is ignored; it's there only to satisfy the XMLReader interface
    
    Specified by:
    
    parse in interface XMLReader
    
    Throws:
    
    SAXException
  - parse
```
public void parse(String source)
           throws SAXException
```
    Parse from SystemId. The SystemId is ignored; it's there only to satisfy the XMLReader interface
    
    Specified by:
    
    parse in interface XMLReader
    
    Throws:
    
    SAXException
  - parse

                   throws SAXNotRecognizedException
```
    SAX2: Tells the value of the specified feature flag.
    
    Specified by:
    
    getFeature in interface XMLReader
    
    Throws:
    
    SAXNotRecognizedException - thrown if the feature flag is neither built in, nor yet assigned.

                       SAXNotSupportedException

    setFeature in interface XMLReader
    
    Throws:
    
    SAXNotRecognizedException
