XMLFilter (Java SE 9 & JDK 9 )

All Superinterfaces:

XMLReader

All Known Implementing Classes:

XMLFilterImpl
```
public interface XMLFilter
extends XMLReader
```
Interface for 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.

An XML filter is like an XML reader, except that it obtains its events from another XML reader rather than a primary source like an XML document or database. Filters can modify a stream of events as they pass on to the final application.

The XMLFilterImpl helper class provides a convenient base for creating SAX2 filters, by passing on all EntityResolver, DTDHandler, ContentHandler and ErrorHandler events automatically.

Since:

1.4, SAX 2.0

- Method Detail
  - setParent
```
void setParent(XMLReader parent)
```
    Set the parent reader.
    This method allows the application to link the filter to a parent reader (which may be another filter). The argument may not be null.
    
    Parameters:
    
    parent - The parent reader.
  - getParent
```
XMLReader getParent()
```
    Get the parent reader.
    This method allows the application to query the parent reader (which may be another filter). It is generally a bad idea to perform any operations on the parent reader directly: they should all pass through this filter.
    
    Returns:
    
    The parent filter, or null if none has been set.
