Method Summary

<V,T extends Throwable> V	call(Callable<V,T> callable) Makes a remote procedure call.
<V,T extends Throwable> Future<V>	callAsync(Callable<V,T> callable) Makes an asynchronous remote procedure call.
void	close() Performs an orderly shut down of this channel (and the remote peer.)
<T> T	export(Class<T> type, T instance) Exports an object for remoting to the other Channel by creating a remotable proxy.
void	join() Waits for this Channel to be closed down.
void	join(long timeout) Waits for this Channel to be closed down, but only up the given milliseconds.

Method Detail

call

<V,T extends Throwable> V call(Callable<V,T> callable)
       throws IOException,
              T extends Throwable,
              InterruptedException

Makes a remote procedure call.

Sends Callable to the remote system, executes it, and returns its result.

Throws:

InterruptedException - If the current thread is interrupted while waiting for the completion.

IOException - If there's any error in the communication between Channels.

T extends Throwable

callAsync

<V,T extends Throwable> Future<V> callAsync(Callable<V,T> callable)
                    throws IOException

Makes an asynchronous remote procedure call.

Similar to call(Callable) but returns immediately. The result of the Callable can be obtained through the Future object.

Returns:

The Future object that can be used to wait for the completion.

Throws:

IOException - If there's an error during the communication.

close

void close()
           throws IOException

Performs an orderly shut down of this channel (and the remote peer.)

Throws:

IOException - if the orderly shut-down failed.

join

void join()
          throws InterruptedException

Waits for this Channel to be closed down. The close-down of a Channel might be initiated locally or remotely.

Throws:

InterruptedException - If the current thread is interrupted while waiting for the completion.

Since:

1.300

join

void join(long timeout)
          throws InterruptedException

Waits for this Channel to be closed down, but only up the given milliseconds.

Throws:

InterruptedException - If the current thread is interrupted while waiting for the completion.

Since:

1.300

export

<T> T export(Class<T> type,
             T instance)

Exports an object for remoting to the other Channel by creating a remotable proxy.

All the parameters and return values must be serializable.

Parameters:

type - Interface to be remoted.

Returns:

the proxy object that implements T. This object can be transfered to the other Channel, and calling methods on it from the remote side will invoke the same method on the given local instance object.
