Protected Methods
int	getDefaultPort() Returns the default port for a URL parsed by this handler.
URLConnection	openConnection(URL u, Proxy p) Same as openConnection(URL), except that the connection will be made through the specified proxy; Protocol handlers that do not support proxying will ignore the proxy parameter and make a normal connection.
URLConnection	openConnection(URL u) Opens a connection to the object referenced by the `URL` argument.

From class java.net.URLStreamHandler

boolean	equals(URL u1, URL u2) Provides the default equals calculation.
int	getDefaultPort() Returns the default port for a URL parsed by this handler.
synchronized InetAddress	getHostAddress(URL u) Get the IP address of our host.
int	hashCode(URL u) Provides the default hash calculation.
boolean	hostsEqual(URL u1, URL u2) Compares the host components of two URLs.
URLConnection	openConnection(URL u, Proxy p) Same as openConnection(URL), except that the connection will be made through the specified proxy; Protocol handlers that do not support proxying will ignore the proxy parameter and make a normal connection.
abstract URLConnection	openConnection(URL u) Opens a connection to the object referenced by the `URL` argument.
void	parseURL(URL u, String spec, int start, int limit) Parses the string representation of a `URL` into a `URL` object.
boolean	sameFile(URL u1, URL u2) Compare two urls to see whether they refer to the same file, i.e., having the same protocol, host, port, and path.
void	setURL(URL u, String protocol, String host, int port, String file, String ref) This method is deprecated. Use setURL(URL, String, String, int, String, String, String, String);
void	setURL(URL u, String protocol, String host, int port, String authority, String userInfo, String path, String query, String ref) Sets the fields of the `URL` argument to the indicated values.
String	toExternalForm(URL u) Converts a `URL` of a specific protocol to a `String`.

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Fields

protected String proxy

protected int proxyPort

Public Constructors

public Handler ()

public Handler (String proxy, int port)

Protected Methods

protected int getDefaultPort ()

Returns the default port for a URL parsed by this handler. This method is meant to be overidden by handlers with default port numbers.

Returns

the default port for a URL parsed by this handler.

protected URLConnection openConnection (URL u, Proxy p)

Same as openConnection(URL), except that the connection will be made through the specified proxy; Protocol handlers that do not support proxying will ignore the proxy parameter and make a normal connection. Calling this method preempts the system's default ProxySelector settings.

Parameters

u	the URL that this connects to.
p	the proxy through which the connection will be made. If direct connection is desired, Proxy.NO_PROXY should be specified.

Returns

a URLConnection object for the URL.

Throws

IOException

protected URLConnection openConnection (URL u)

Opens a connection to the object referenced by the URL argument. This method should be overridden by a subclass.

If for the handler's protocol (such as HTTP or JAR), there exists a public, specialized URLConnection subclass belonging to one of the following packages or one of their subpackages: java.lang, java.io, java.util, java.net, the connection returned will be of that subclass. For example, for HTTP an HttpURLConnection will be returned, and for JAR a JarURLConnection will be returned.

Parameters

u	the URL that this connects to.

Returns

a URLConnection object for the URL.

Throws

IOException
