```
public class XMLFilterImpl
extends Object
implements XMLFilter, EntityResolver, DTDHandler, ContentHandler, ErrorHandler
```
Base class for deriving an XML filter.
This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY. See http://www.saxproject.org for further information.

This class is designed to sit between an XMLReader and the client application's event handlers. By default, it does nothing but pass requests up to the reader and events on to the handlers unmodified, but subclasses can override specific methods to modify the event stream or the configuration requests as they pass through.

Since:

SAX 2.0

- Constructor Detail
  - XMLFilterImpl
```
public XMLFilterImpl()
```
    Construct an empty XML filter, with no parent.
    This filter will have no parent: you must assign a parent before you start a parse or do any configuration with setFeature or setProperty, unless you use this as a pure event consumer rather than as an XMLReader.
    
    See Also:
    XMLReader.setFeature(java.lang.String, boolean), XMLReader.setProperty(java.lang.String, java.lang.Object), setParent(org.xml.sax.XMLReader)
  - XMLFilterImpl
```
public XMLFilterImpl(XMLReader parent)
```
    Construct an XML filter with the specified parent.
    
    See Also:
    setParent(org.xml.sax.XMLReader), getParent()
- Method Detail
  - setParent
```
public void setParent(XMLReader parent)
```
    Set the parent reader.
    This is the XMLReader from which this filter will obtain its events and to which it will pass its configuration requests. The parent may itself be another filter.
    
    If there is no parent reader set, any attempt to parse or to set or get a feature or property will fail.
    
    Specified by:
    
    setParent in interface XMLFilter
    
    Parameters:
    parent - The parent XML reader.
    See Also:
    getParent()
  - getParent
```
public XMLReader getParent()
```
    Get the parent reader.
    
    Specified by:
    
    getParent in interface XMLFilter

    setFeature in interface XMLReader
    
    Parameters:
    name - The feature name.
    value - The requested feature value.
    
    Throws:
