Method Detail

exportSkeleton

public void exportSkeleton(Skeleton skel)

getSkeleton

public Skeleton getSkeleton(int uid)

getStub

public Stub getStub(int tid,
           int uid)

listen

public void listen()

stopListening

public void stopListening()

prepareOutgoingInvoke

public ResultCell prepareOutgoingInvoke(Stub self,
                               int classId,
                               int methodId)
                                 throws java.io.IOException

First call made by a stub. It will allocate the ResultCell and the output buffer for the outgoing packet. It will also check if this out-going remote invocation is part of a global execution already or not. If not, a global execution (distributed thread) is set, other the current one is reused.

Throws:

java.io.IOException

searchCell

public ResultCell searchCell(int cmdId)

swizzle

public Stub swizzle(int tid,
           int uid)

dispatchInvocation

protected abstract void dispatchInvocation(ResultCell rcell)
                                    throws java.lang.Exception

Throws:

java.lang.Exception

wireExceptionNotify

protected void wireExceptionNotify(java.lang.Exception ex)

A Wire-related exception occurred. We will consider that we have lost the connection. All stubs will be revoked... allowing higher-level listener to pick up that some remote objects have been revoked through the StubListener mechanism. Log at lower priority than a standard exception, since this is the client quit mechanism too.
