java.lang.Object | +----java.net.URLStreamHandler
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.
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.
