• Field Detail

  • MODE_NORMAL

    public static final int MODE_NORMAL

    This mode indicates that the stream sends and receives packets at the same time. This is the initial mode for new streams.

  • MODE_SEND_ONLY

    public static final int MODE_SEND_ONLY

    This mode indicates that the stream only sends packets.

• Method Detail

  • getLocalAddress

    public InetAddress getLocalAddress()

    Returns the network address of the local host.

  • getLocalPort

    public int getLocalPort()

    Returns the network port of the local host.

  • getRemoteAddress

    public InetAddress getRemoteAddress()

    Returns the network address of the remote host or null if the stream is not associated.

  • getRemotePort

    public int getRemotePort()

    Returns the network port of the remote host or -1 if the stream is not associated.

  • isBusy

    public boolean isBusy()

    Returns true if the stream is busy. In this case most of the setter methods are disabled. This method is intended to be overridden by subclasses.

  • getMode

    public int getMode()

    Returns the current mode.

  • setMode

    public void setMode(int mode)

    Changes the current mode. It must be one of MODE_NORMAL, MODE_SEND_ONLY, and MODE_RECEIVE_ONLY.

    Parameters:

    mode - The mode to change to.

    Throws:

    IllegalArgumentException - if the mode is invalid.

    IllegalStateException - if the stream is busy.

    See Also:

    isBusy()

  • associate

    public void associate(InetAddress address,
                 int port)

    Associates with a remote host. This defines the destination of the outgoing packets.

    Parameters:

    address - The network address of the remote host.

    port - The network port of the remote host.

    Throws:

    IllegalArgumentException - if the address is not supported or the port is invalid.

    IllegalStateException - if the stream is busy.

    See Also:

    isBusy()

  • release

    public void release()

    Releases allocated resources. The stream becomes inoperable after calling this method.

    Throws:

    IllegalStateException - if the stream is busy.

    See Also:

    isBusy()

  • finalize

    protected void finalize()
                     throws Throwable

    Description copied from class: Object
    Invoked when the garbage collector has detected that this instance is no longer reachable. The default implementation does nothing, but this method can be overridden to free resources.

    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.

    Overrides:

    finalize in class Object

    Throws:

    Throwable
