public void setParent(org.xml.sax.XMLReader parent)
org.xml.sax.XMLFilter
This method allows the application to link the filter to a parent reader (which may be another filter). The argument may not be null.
setParent

org.xml.sax.XMLFilter
parent
- The parent reader.public org.xml.sax.XMLReader getParent()
org.xml.sax.XMLFilter
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.

public boolean getFeature(java.lang.String name) throws org.xml.sax.SAXNotRecognizedException, org.xml.sax.SAXNotSupportedException
org.xml.sax.XMLReader
The feature name is any fully-qualified URI. It is possible for an XMLReader to recognize a feature name but to be unable to return its value; this is especially true in the case of an adapter for a SAX1 Parser, which has no way of knowing whether the underlying parser is performing validation or expanding external entities.
All XMLReaders are required to recognize the http://xml.org/sax/features/namespaces and the http://xml.org/sax/features/namespace-prefixes feature names.
Some feature values may be available only in specific contexts, such as before, during, or after a parse.
Typical usage is something like this:
XMLReader r = new MySAXDriver(); // try to activate validation try { r.setFeature("http://xml.org/sax/features/validation", true); } catch (SAXException e) { System.err.println("Cannot activate validation."); } // register event handlers r.setContentHandler(new MyContentHandler()); r.setErrorHandler(new MyErrorHandler()); // parse the first document try { r.parse("http://www.foo.com/mydoc.xml"); } catch (IOException e) { System.err.println("I/O exception reading XML document"); } catch (SAXException e) { System.err.println("XML exception reading document."); }
Implementors are free (and encouraged) to invent their own features, using names built on their own URIs.

The feature name is any fully-qualified URI. It is
possible for an XMLReader to recognize a feature name but
to be unable to set its value; this is especially true
in the case of an adapter for a SAX1 Parser
,
which has no way of affecting whether the underlying parser is
validating, for example.
All XMLReaders are required to support setting http://xml.org/sax/features/namespaces to true and http://xml.org/sax/features/namespace-prefixes to false.
Some feature values may be immutable or mutable only in specific contexts, such as before, during, or after a parse.

The property name is any fully-qualified URI. It is
possible for an XMLReader to recognize a property name but
to be unable to return its state; this is especially true
in the case of an adapter for a SAX1 Parser
.
XMLReaders are not required to recognize any specific property names, though an initial core set is documented for SAX2.
Some property values may be available only in specific contexts, such as before, during, or after a parse.

The property name is any fully-qualified URI. It is
possible for an XMLReader to recognize a property name but
to be unable to set its value; this is especially true
in the case of an adapter for a SAX1 Parser
.
XMLReaders are not required to recognize setting any specific property names, though a core set is provided with SAX2.
Some property values may be immutable or mutable only in specific contexts, such as before, during, or after a parse.
This method is also the standard mechanism for setting extended handlers.

org.xml.sax.XMLReader
If the application does not register an entity resolver, the XMLReader will perform its own default resolution.
Applications may register a new or different resolver in the middle of a parse, and the SAX parser must begin using the new resolver immediately.

If the application does not register a DTD handler, all DTD events reported by the SAX parser will be silently ignored.

public void setErrorHandler(org.xml.sax.ErrorHandler handler)
org.xml.sax.XMLReader
If the application does not register an error handler, all error events reported by the SAX parser will be silently ignored; however, normal processing may not continue. It is highly recommended that all SAX applications implement an error handler to avoid unexpected bugs.
Applications may register a new or different handler in the middle of a parse, and the SAX parser must begin using the new handler immediately.

public void parse(org.xml.sax.InputSource input) throws java.io.IOException, org.xml.sax.SAXException
org.xml.sax.XMLReader
The application can use this method to instruct the XML reader to begin parsing an XML document from any valid input source (a character stream, a byte stream, or a URI).
Applications may not invoke this method while a parse is in progress (they should create a new XMLReader instead for each nested XML document). Once a parse is complete, an application may reuse the same XMLReader object, possibly with a different input source.
During the parse, the XMLReader will provide information about the XML document through the registered event handlers.
This method is synchronous: it will not return until parsing has ended. If a client application wants to terminate parsing early, it should throw an exception.

public void parse(java.lang.String systemId) throws java.io.IOException, org.xml.sax.SAXException
org.xml.sax.XMLReader
This method is a shortcut for the common case of reading a document from a system identifier. It is the exact equivalent of the following:
parse(new InputSource(systemId));
If the system identifier is a URL, it must be fully resolved by the application before it is passed to the parser.
