public interface XMLFilter
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.

Method Detail |
---|
void setParent(XMLReader parent)
This method allows the application to link the filter to a parent reader (which may be another filter). The argument may not be null.
parent
- The parent reader.XMLReader getParent()
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.
