SaxParser.getFeature

Look up the value of a feature flag.

<p>The feature name is any fully-qualified URI. It is possible for an XMLReader to recognize a feature name but temporarily be unable to return its value. Some feature values may be available only in specific contexts, such as before, during, or after a parse. Also, some feature values may not be programmatically accessible. (In the case of an adapter for SAX1 {@link Parser}, there is no implementation-independent way to expose whether the underlying parser is performing validation, expanding external entities, and so forth.) </p>

<p>All XMLReaders are required to recognize the http://xml.org/sax/features/namespaces and the http://xml.org/sax/features/namespace-prefixes feature names.</p>

<p>Typical usage is something like this:</p>

<pre> 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."); } </pre>

<p>Implementors are free (and encouraged) to invent their own features, using names built on their own URIs.</p>

@param name The feature name, which is a fully-qualified URI. @return The current value of the feature (true or false). @exception org.xml.sax.SAXNotRecognizedException If the feature value can't be assigned or retrieved. @exception org.xml.sax.SAXNotSupportedException When the XMLReader recognizes the feature name but cannot determine its value at this time. @see #setFeature
