- All Superinterfaces:
XMLReader
- All Known Implementing Classes:
XMLFilterImpl
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 Details
-
setParent
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.
