permission.
Modifier and Type | Field and Description |
---|---|
static int |
MODE_NORMAL
This mode indicates that the stream sends and receives packets at the
same time.

void |
associate(InetAddress address,
int port)
Associates with a remote host.
|
protected void |
finalize()
Invoked when the garbage collector has detected that this instance is no longer reachable.
|
InetAddress |
getLocalAddress()
Returns the network address of the local host.
|
int |
getLocalPort()
Returns the network port of the local host.
|
int |
getMode()
Returns the current mode.
|
InetAddress |
getRemoteAddress()
Returns the network address of the remote host or
null if the
stream is not associated. |
int |
getRemotePort()
Returns the network port of the remote host or
-1 if the stream
is not associated. |
boolean |
isBusy()
Returns
true if the stream is busy. |

Object
Note that objects that override finalize
are significantly more expensive than
objects that don't. Finalizers may be run a long time after the object is no longer
reachable, depending on memory pressure, so it's a bad idea to rely on them for cleanup.
Note also that finalizers are run on a single VM-wide finalizer thread,
so doing blocking work in a finalizer is a bad idea. A finalizer is usually only necessary
for a class that has a native peer and needs to call a native method to destroy that peer.
Even then, it's better to provide an explicit close
method (and implement
Closeable
), and insist that callers manually dispose of instances. This
works well for something like files, but less well for something like a BigInteger
where typical calling code would have to deal with lots of temporaries. Unfortunately,
code that creates lots of temporaries is the worst kind of code from the point of view of
the single finalizer thread.
If you must use finalizers, consider at least providing your own
ReferenceQueue
and having your own thread process that queue.
Unlike constructors, finalizers are not automatically chained. You are responsible for
calling super.finalize()
yourself.
Uncaught exceptions thrown by finalizers are ignored and do not terminate the finalizer thread. See Effective Java Item 7, "Avoid finalizers" for more.
