java.lang.Object
- javax.xml.parsers.DocumentBuilder

```
public abstract class DocumentBuilder
extends Object
```
Defines the API to obtain DOM Document instances from an XML document. Using this class, an application programmer can obtain a Document from XML.
An instance of this class can be obtained from the DocumentBuilderFactory.newDocumentBuilder() method. Once an instance of this class is obtained, XML can be parsed from a variety of input sources. These input sources are InputStreams, Files, URLs, and SAX InputSources.
Note that this class reuses several classes from the SAX API. This does not require that the implementor of the underlying DOM implementation use a SAX parser to parse XML document into a Document. It merely requires that the implementation communicate with the application using these existing APIs.

```
    Protected constructor

  - reset
```
public void reset()
```
    Reset this DocumentBuilder to its original configuration.
    
    DocumentBuilder is reset to the same state as when it was created with DocumentBuilderFactory.newDocumentBuilder(). reset() is designed to allow the reuse of existing DocumentBuilders thus saving resources associated with the creation of new DocumentBuilders.
    
    The reset DocumentBuilder is not guaranteed to have the same EntityResolver or ErrorHandler Objects, e.g. Object.equals(Object obj). It is guaranteed to have a functionally equal EntityResolver and ErrorHandler.
    
    Throws:
    
    UnsupportedOperationException - When implementation does not override this method.
    Since:
    
    1.5
