The abstract class ContentHandler is the superclass
of all classes that read an Object from a
URLConnection.
An application does not generally call the
getContent method in this class directly. Instead, an
application calls the getContent method in class
URL or in URLConnection.
The application's content handler factory (an instance of a class that
implements the interface ContentHandlerFactory set
up by a call to setContentHandler) is
called with a String giving the MIME type of the
object being received on the socket. The factory returns an
instance of a subclass of ContentHandler, and its
getContent method is called to create the object.
If no content handler could be found, URLConnection will
look for a content handler in a user-defineable set of places.
By default it looks in sun.net.www.content, but users can define a
vertical-bar delimited set of class prefixes to search through in
addition by defining the java.content.handler.pkgs property.
The class name must be of the form:
{package-prefix}.{major}.{minor}
e.g.
YoyoDyne.experimental.text.plain
If the loading of the content handler class would be performed by
a classloader that is outside of the delegation chain of the caller,
the JVM will need the RuntimePermission "getClassLoader".
