12.5 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 book 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.
