Batching I

One form of batching optimization is to combine multiple messages into one message. For the examples we've examined so far, this is easily illustrated. Simply add a method to access all attributes of the server object in one access:^[2]

^[2] The various communications layers handle distributed classes differently. This tutorial is not a tutorial on CORBA or RMI, so I have elected to show a standard Java representation of the required classes.

class ServerObjectDataCopy
{
 public boolean bool;
 public int number;
 public String string;
}
public class ServerObjectImpl
{
 public ServerObjectDataCopy getAll( );
 ...

Using this method to batch the three access methods into one access makes the combined (uncached) access of all the attributes three times faster.
