[jbosscache-dev] NodeData streaming marker

Hi, As some of you are aware we talked about introducing a delimiter node inserted between transient and persistent state. Since we have to look for this node in the stream during streaming state transfer the search should be very very efficient operation. Note that this is done only for streaming state transfer and cacheloader implementations are unaware of this. Optimal solution IMO would be to extend NodeData class with NodeDataMarker subclass and introduce a method public boolean NodeData.isMarker() that would return false in NodeData superclass and true in NodeDataMarker subclass of NodeData. We would write an instance of NodeDataMarker as a delimiter between transient and persistent part of the stream. As we read instances of NodeData in StreamingStateTransferIntegrator the search for NodeDataMarker is fast and should not affect overall performance at all. If I do not hear any objections or better proposals I will commit this on Monday. Vladimir
