java.lang.Object | +----java.net.URLStreamHandler
The abstract class URLStreamHandler is the common
superclass for all stream protocol handlers. A stream protocol
handler knows how to make a connection for a particular protocol
type, such as http, ftp, or
gopher.
In most cases, an instance of a URLStreamHandler
subclass is not created directly by an application. Rather, the
first time a protocol name is encountered when constructing a
URL, the appropriate stream protocol handler is
automatically loaded.
URL argument.
URL into a
URL object.
URL argument to the
indicated values.
URL of a specific protocol to a
String.
public URLStreamHandler()
protected abstract URLConnection openConnection(URL u) throws IOException
URL argument.
This method should be overridden by a subclass.
URLConnection object for the
URL.
protected void parseURL(URL u,
String spec,
int start,
int limit)
URL into a
URL object.
If there is any inherited context, then it has already been
copied into the URL argument.
The parseURL method of
URLStreamHandler parses the string representation
as if it were an http specification. Most URL
protocol families have a similar parsing. A stream protocol
handler for a protocol that has a different syntax must
override this routine.
If the file component of the URL argument contains a
question mark (as with CGI HTTP URLs), the context is
considered to be the URL's file component up to the first /
before the question mark, not including the question mark or
the directory before it. For example, if the URL was:
http://www.foo.com/dir/cgi-bin?foo=bar/bazand the spec argument was
quux.htmlthe resulting URL would be:
http://www.foo.com/dir/quux.html.
URL to receive the result of parsing
the spec.
String representing the URL that
must be parsed.
:' (if there is
one) that specifies the determination of the protocol name.
#"
character, if present. All information after the sharp sign
indicates an anchor.
protected String toExternalForm(URL u)
URL of a specific protocol to a
String.
URL argument.
protected void setURL(URL u,
String protocol,
String host,
int port,
String file,
String ref)
URL argument to the
indicated values. Only classes derived from URLStreamHandler
are supposed to be able to call the set method on a URL.
