SimpleStoreOutputStream

public abstract class StoreOutputStream
extends java.io.OutputStream

Extension of Java's OutputStream to support aborting a created but not yet closed object. The purpose is to tell the ObjectStoreService that the object this stream writes to should never become visible because it is not valid. See description of abort() for details. If abort() is not called before OutputStream.close() the object will become visible in the store after the call to OutputStream.close(). The IOExceptions thrown by the OutputStream.write(int), OutputStream.write(byte[]), OutputStream.write(byte[], int, int), OutputStream.flush(), and OutputStream.close() exceptions may contain ObjectStoreExceptions as cause which describe the error in more detail.
