Interface for an XML filter.This module, both source code and documentation, is in the Public Domain, and comes withNO WARRANTY. Seehttp://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,ContentHandlerandErrorHandlerevents 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.
