Method Detail

waitForNext

public boolean waitForNext(int sequence)
                    throws InterruptedException

Is called by methods which cannot yield control of the current thread. Call finished after invoking method.

Returns:

false if session was closed because of an unfilled hole in the ordered sequence

Throws:

InterruptedException

isNext

public boolean isNext(int sequence)

Is called by asynchronous methods to prevent too many threads from accumulating. If false is returned, call addPendingMethod. If true is returned, call finished after invoking asynchronous method.

finished

public void finished(int sequence)

addPendingMethod

public void addPendingMethod(int sequence,
                             Method method,

                             Object[] params,
                             VersionedIdentifier disposeId)

addPendingMethod

public <V> void addPendingMethod(int sequence,
                                 Method method,
                                 Object instance,
                                 Object[] params,
                                 VersionedIdentifier disposeId,
                                 RemoteCompletion<V> completion)

Call if method returns a Future or Completion.
