Interface java.rmi.server.RemoteCall

public interface RemoteCall

RemoteCall is an abstraction used solely by the implementation (stubs and skeletons of remote objects) to carry out a call to a remote object.

done(): Allow cleanup after the remote call has completed.
executeCall(): Do whatever it takes to execute the call.
getInputStream(): Get the InputStream that the stub/skeleton should get results/arguments from.
getOutputStream(): Return the output stream the stub/skeleton should put arguments/results into.
getResultStream(boolean): Returns an output stream (may put out header information relating to the success of the call).
releaseInputStream(): Release the input stream.
releaseOutputStream(): Release the output stream; in some transports this would release the stream.

getOutputStream

 public abstract ObjectOutput getOutputStream() throws IOException

Return the output stream the stub/skeleton should put arguments/results into.

Throws: IOException: if an I/O error occurs.

releaseOutputStream

 public abstract void releaseOutputStream() throws IOException

Release the output stream; in some transports this would release the stream.

Throws: IOException: if an I/O error occurs.

getInputStream

 public abstract ObjectInput getInputStream() throws IOException

Get the InputStream that the stub/skeleton should get results/arguments from.

Throws: IOException: if an I/O error occurs.

releaseInputStream

 public abstract void releaseInputStream() throws IOException

Release the input stream. This would allow some transports to release the channel early.

Throws: IOException: if an I/O error occurs.

getResultStream

 public abstract ObjectOutput getResultStream(boolean success) throws IOException, StreamCorruptedException

Returns an output stream (may put out header information relating to the success of the call). Should only succeed once per remote call.

Parameters:: success - If true, indicates normal return, else indicates exceptional return.
Throws: IOException: if an I/O error occurs.
Throws: StreamCorruptedException: If already been called.

executeCall

 public abstract void executeCall() throws Exception

Do whatever it takes to execute the call.

Throws: Exception: if a general exception occurs.

done

 public abstract void done() throws IOException

Allow cleanup after the remote call has completed.

Throws: IOException: if an I/O error occurs.
