Class ContentHandler 
java.lang.Object
java.net.ContentHandler
- public abstract class ContentHandler
- extends java.lang.Object
This is an abstract class that is the superclass for classes that read
objects from URL's. Calling the getContent() method in the
URL class or the URLConnection class will cause
an instance of a subclass of ContentHandler to be created for
the MIME type of the object being downloaded from the URL. Thus, this
class is seldom needed by applications/applets directly, but only
indirectly through methods in other classes.

getContent
public abstract java.lang.Object getContent(URLConnection urlc)
throws java.io.IOException
- This method reads from the
InputStream of the passed in URL
connection and uses the data downloaded to create an Object
represening the content. For example, if the URL is pointing to a GIF
file, this method might return an Image object. This method
must be implemented by subclasses.
getContent
public java.lang.Object getContent(URLConnection urlc,
java.lang.Class[] classes)
throws java.io.IOException
- This method reads from the
InputStream of the passed in URL
connection and uses the data downloaded to create an Object
represening the content. For example, if the URL is pointing to a GIF
file, this method might return an Image object. This method
must be implemented by subclasses. This method uses the list of
supplied classes as candidate types. If the data read doesn't match
any of the supplied type, null is returned.
