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

```
public abstract class SAXParser
extends Object
```
Defines the API that wraps an XMLReader implementation class. In JAXP 1.0, this class wrapped the Parser interface, however this interface was replaced by the XMLReader. For ease of transition, this class continues to support the same name and interface as well as supporting new methods. An instance of this class can be obtained from the SAXParserFactory.newSAXParser() 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.
This static method creates a new factory instance based on a system property setting or uses the platform default if no property has been defined.
The system property that controls which Factory implementation to create is named "javax.xml.parsers.SAXParserFactory". This property names a class that is a concrete subclass of this abstract class. If no property is defined, a platform default will be used.
As the content is parsed by the underlying parser, methods of the given HandlerBase or the DefaultHandler are called.
Implementors of this class which wrap an underlaying implementation can consider using the ParserAdapter class to initially adapt their SAX1 implementation to work under this revised class.

- Constructor Detail
  - SAXParser
```
protected SAXParser()
```
    Protected constructor to prevent instaniation. Use SAXParserFactory.newSAXParser().
- Method Detail
  - reset
```
public void reset()
```
    Reset this SAXParser to its original configuration.
    
    SAXParser is reset to the same state as when it was created with SAXParserFactory.newSAXParser(). reset() is designed to allow the reuse of existing SAXParsers thus saving resources associated with the creation of new SAXParsers.
    
    The reset SAXParser is not guaranteed to have the same Schema Object, e.g. Object.equals(Object obj). It is guaranteed to have a functionally equal Schema.
    
    Throws:
    
    UnsupportedOperationException - When Implementations do not override this method

                                 SAXNotSupportedException
```
    Sets the particular property in the underlying implementation of XMLReader. A list of the core features and properties can be found at http://sax.sourceforge.net/?selected=get-set.
    
    All implementations that implement JAXP 1.5 or newer are required to support the XMLConstants.ACCESS_EXTERNAL_DTD and XMLConstants.ACCESS_EXTERNAL_SCHEMA properties.
    - Setting the XMLConstants.ACCESS_EXTERNAL_DTD property restricts the access to external DTDs, external Entity References to the protocols specified by the property. If access is denied during parsing due to the restriction of this property, SAXException will be thrown by the parse methods defined by SAXParser.
      
      Setting the XMLConstants.ACCESS_EXTERNAL_SCHEMA property restricts the access to external Schema set by the schemaLocation attribute to the protocols specified by the property. If access is denied during parsing due to the restriction of this property, SAXException will be thrown by the parse methods defined by the SAXParser.
    Parameters:
    name - The name of the property to be set.
    value - The value of the property to be set.
    
    Throws:
    
    SAXNotRecognizedException - When the underlying XMLReader does not recognize the property name.
    
    SAXNotSupportedException - When the underlying XMLReader recognizes the property name but doesn't support the property.
    See Also:
    XMLReader.setProperty(java.lang.String, java.lang.Object)
  - getProperty
```
public abstract Object getProperty(String name)
                            throws SAXNotRecognizedException,

```
    Returns the particular property requested for in the underlying implementation of XMLReader.
    
    Parameters:
    name - The name of the property to be retrieved.
    
    Returns:
    Value of the requested property.
    
    Throws:
    
    SAXNotRecognizedException - When the underlying XMLReader does not recognize the property name.
    
    SAXNotSupportedException - When the underlying XMLReader recognizes the property name but doesn't support the property.
    See Also:
    XMLReader.getProperty(java.lang.String)
  - getSchema
```
public Schema getSchema()
```
    Get a reference to the the Schema being used by the XML processor.
    
    If no schema is being used, null is returned.
    
    Returns:
    Schema being used or null if none in use
    
    Throws:
    
    UnsupportedOperationException - When implementation does not override this method
    Since:
    
    1.5
  - isXIncludeAware
```
public boolean isXIncludeAware()
```
    Get the XInclude processing mode for this parser.
    
    Returns:
    the return value of the SAXParserFactory.isXIncludeAware() when this parser was created from factory.
    
    Throws:
    
    UnsupportedOperationException - When implementation does not override this method
    Since:
    
    1.5
