      jsim.jmessage.Result

All Implemented Interfaces:

java.io.Serializable

public class Result
extends Message

The Result class is a JSIM message type representing the query result returned by the DBAgent. It may contain a simple message indicating if the query is successful or not. Or it may encapsulate a Java ResultSet object. In the former case, the action type would be "Information". In the latter case, the action type would be either "Sequence number" or "Normal result".
